Liam Digby is 12 years old and might be the youngest person to ever be launched into space. Currently, he talks into his phone, recording everything as he and four others aboard the rocket dubbed Infinite Possibility careen through space. Due to an error, it drifted out of orbit, and now Liam is certain that they’re all doomed. However, he hopes that his message will reach his parents somehow, and he (sort of) regrets lying his way into the space mission. He said he was going on a school trip, but instead took advantage of his extreme height to fake his way into the mission. The mission secretly took off from China.
Liam is surprised to find that in some sense he enjoys the experience, because even though he’s doomed, he gets to see the stars and planets in a whole new way. Unfortunately, Earth is nowhere to be seen, and one of the other passengers thinks that they may have gone through a black hole.
The narrative flashes back to the events that led up to his trip to space. The day Liam realizes he’s growing up is the day that he attends the fair with his class and goes on a ride called the Cosmic. None of his peers is allowed on it because they’re all too short, but Liam is tall, and the attendant thinks he’s an adult. Liam goes on the ride with his dad, and it shoots them into the air and back down again. It makes Liam feel brand new and alive.
When the class leaves, Liam realizes that the man at the gate also thinks Liam is an adult, and he uses the chance to run back to the ride. He rides it five more times, and when his father finally comes back and finds him, he’s furious. The ride attendant points to Liam’s “beard” and says he thought Liam was an adult. Liam never worried because he always knew his dad would come for him.
Now, in space, he knows that isn’t possible, and he knows he’s no longer a kid.
In another flashback, Liam tries to shave off his stubble after people start making fun of him, but he gives himself too many cuts, so his father teaches him. Liam’s mother worries about him growing so quickly and takes him to several doctors, but none of them find anything wrong. When Liam begins school at Waterloo High, the headmistress thinks he’s a new teacher. She takes Liam to the staff room and introduces him to the other staff. Liam tries to tell her that he's in seventh grade, but she doesn’t seem to hear him.
At a school assembly, the headmistress introduces Liam in front of the whole school. He makes a speech about all the places named Waterloo in the world, and invites the students to join him on an adventure. They all follow him outside into the school yard, where the actual new teacher is waiting to get inside. The headmistress is initially confused and then angry, but Liam insists that he never lied about being a teacher.
Liam’s teacher tells his father that he doesn’t fit in and has no friends at school, but Liam prefers the company of his online friends anyway, because they don’t judge him for his height. Regardless, his father signs him up for a drama club, and one of Liam’s acquaintances from school, a girl named Florida, also joins it. Liam is chosen to be the Big Friendly Giant (BFG) in the upcoming play. After the first day, Liam and Florida discover that people seem to think they’re father and daughter, and decide to take advantage of it.
Liam describes the feeling of privilege and the strong desire to keep pushing the boundaries to find out how much he can get away with. At one point, the two friends go to a car dealership, and Liam fools the man into thinking he’s old enough to drive. Just as Liam gets behind the wheel of a Porsche, his father appears, angry again. On the way home, Liam asks how his father knew where to find him, and Liam’s father, who is a taxi driver, explains that it’s just “what dads do” (47).
Liam admits that he’s grateful his dad appeared in that moment, but now that he’s out in space, he knows that his dad can’t save him.
Liam’s dad decides that the family needs a vacation and hopes that the time away will relieve some of their stress. The family visits a travel agent, but Liam’s mother finds an issue with every place the agent suggests. Finally, the family decides to renovate the kitchen instead, which Liam finds much less exciting. In drama club, the night of the play arrives, and Liam sits in his room before the play, imagining himself orbiting the sun in space.
Liam spends a lot of time surfing the internet on an app called DraxWorld. He usually looks at theme parks around the world or at all the places in the world named Waterloo. Before the play, a woman calls him asking about his internet habits and his hopes for his children. When Liam realizes that the woman thinks he’s a father, he answers that he wants his children to see the world as one big thrill. After the call, Liam has a feeling that something amazing is about to happen. Just before heading onstage, Liam receives a text inviting him and his child to participate in a contest to test the world’s greatest thrill ride ever: a rocket ship set to launch out of China. Liam shows his dad the message, but his dad dismisses it as a scam.
Later, Liam’s dad invites him to play Monopoly, but Liam complains that it’s boring and pointless and goes to his room to play World of Warcraft instead. His father comes in and tries to show an interest in Liam’s hobby. However, when he sees Liam’s avatar, which is his opposite (short, magical, many friends), he becomes uncomfortable and leaves. Liam plans to call the contest line the following day.
Liam calls the number for the contest and is put on hold. The hold music is Gustav Holst’s The Planets. He’s on hold for hours, and during math class, his teacher hears the music and feels inspired to do a lesson on the planets, which Liam loves. Throughout the day, contest winners are announced over text, including Anna from Hamburg, Germany, and her father; a boy named Samson Two from Waterloo in Sierra Leone; Max and his father from France; and Hasan and his father from Bosnia, who bought their ticket from Anna. Liam realizes that only one spot is left, but when he finally gets through on the call, his teacher takes his phone and hangs up.
That night, Liam gets a call from Drax Communications, telling him that he won and asking about his child. Liam says he has a daughter named Florida. After the call, he realizes that he needs to train himself on being a dad, so he starts practicing talking, walking, and acting like his own father. His next task is to find himself a “daughter.”
Ever since the Porsche incident, Florida has avoided Liam, but he traps her into talking to him at drama club. The two are paired up and told to act like a father and daughter, and Liam uses the chance to tell Florida about the theme park. She continually declines and reminds him that he isn’t a real dad, adding that the last time they tried something like this, they nearly got hurt. Liam follows Florida home, and when he mentions a limousine might be involved, Florida suddenly perks up. She tells Liam she’ll consider going, and says nothing more.
One emerging theme in the opening chapters is Growing Up and Becoming Responsible. Liam’s unusual height causes people to treat him like an adult, creating confusion in how he’s perceived and how he behaves. At the same time, Liam begins physically growing up; he starts shaving, to his mother’s shock, as she thinks he’s growing too fast. Previously, Liam resisted the idea of growing up, since it involved more responsibility, but when he discovers that he can get away with things by pretending to be a grown-up, he begins to use his height to his advantage, which isn’t responsible and thus angers his father and other adults. As future chapters explore, however, going into space makes him embrace real responsibility by taking care of others, and thus helps him develop respect for what being grown up means.
These ideas are closely tied to another of the story’s themes, The Importance of Fatherhood. While Liam is still a child, he’s mistaken for a father and is invited to be “the Greatest Dad Ever” (59) by entering a contest that requires him to pose as a parent. Ironically, Liam embraces this challenge, even trying to master “dadness” by copying the things his own dad says and does. His search for life’s thrills, sparked by riding the Cosmic and wanting more of that “Crispy New World feeling” (16), blurs the line between childhood excitement and adult risk-taking. However, Liam navigates the fine line between being a boy and stepping into adult roles far too soon.
The imagery throughout the story often juxtaposes beauty with danger. One of the most powerful images is Liam’s view of space: “When you’re in it, space looks like the biggest firework display ever—except it’s on pause. It looks like freeze-frame fireworks. Even if you’re Completely Doomed, you’ve got to be impressed” (8). This image captures the surreal nature of space while also reflecting Liam’s ability to find wonder even in life-threatening situations. The feeling he gets from the Cosmic ride offers similar sensory beauty; it gives him a “Crispy New World feeling” (16), in other words, both a physical and emotional thrill. These settings and vivid emotional descriptions emphasize how space and thrill-seeking are both physical states and sources of transformation and wonder.
Several key symbols and motifs appear early on, reinforcing the story’s deeper themes. Space exploration is both literal and metaphorical; it represents adventure and risk, and it links to another of the book’s themes: How a Change in Environment Can Change One’s Perspective. This theme and motif link to the idea of human insignificance, or the perspective one gains from experiencing a broader view. The rocket called Infinite Possibility symbolizes the limitless potential of youth and humanity. Liam is fascinated by space even before he reaches it; for example, he compares sitting in a dark cupboard with a Panda Pop to being alone in orbit, showing his vivid imagination and love for escapism. The World of Warcraft game is another motif, which provides an escape for Liam because it lets him be anything, and his height doesn’t influence how others perceive him. When he tries to share the game with his dad, however, it only emphasizes the disconnect between Liam’s online fantasy and his real-world isolation. Later, when Liam is on hold about the contest, the hold music is Holst’s The Planets, which reinforces the space motif and builds a mood of impending adventure.
Liam is a complex and contradictory protagonist. At 12 years old, he’s extremely tall for his age, and his physical maturity allows him to pose as an adult. His narration is casual and sarcastic, as is evident when he reflects, “To be completely honest, I’m not exactly in the Lake District. To be completely honest, I’m more sort of in space” (3). As in this quote, Liam often blends absurdity with dry humor. He’s impulsive and often doesn’t consider the consequences of his actions, such as when he goes back to ride the Cosmic repeatedly, without telling anyone where he is. He doesn’t mind stretching the truth to get what he wants, including lying his way into the Greatest Dad Ever contest. Liam also has strengths, such as his strong imagination and growing empathy, especially in his friendship with Florida. Early on, the novel establishes Liam as both an immature thrill-seeker and a boy thrust too soon into adulthood.
The novel’s structure builds tension by beginning at the climax, when Liam is lost in space, and then rewinding to reveal how he got there. This creates suspense and gives clues to the decisions that led to the disaster. In a regretful tone, Liam reflects on these decisions: He wishes he had thought “more about the consequences of [his] actions” (30), suggesting early on that he’s aware of his flaws. Much of the tension builds around Liam’s taking advantage of being mistaken for an adult: He begins pretending to be a dad and goes on outings with Florida, leading them closer to the space mission. His calling the contest line, losing his phone to a teacher, and then receiving a callback build momentum toward the impending crisis.
The novel’s style is distinctive for its humor, second-person narration, and self-aware tone. Liam’s narration often feels like a letter to his parents, filled with conversational lines like, “Can you believe that, by the way? We’re in a rocket, spinning hopelessly out of control and into Forever, and what is their chosen course of action? A nap.” (5) The use of capitalization for emphasis, such as, “Being doomed is Not Good. But being weightless is Outstanding” (7), adds personality and intensity to his voice. In addition, literary references play a role in the story; Liam stars in a school play as the Big Friendly Giant (BFG), and the contest structure echoes the one in Roald Dahl’s Charlie and the Chocolate Factory, as an eccentric entrepreneur announces five winners for a mysterious prize. The narration frequently reflects on the past: “I remember thinking, I’ll probably never get out of Bootle [his neighborhood in Liverpool, England] as long as I live. It’s funny to think I am now at this moment further away from Bootle than any other living human” (60). This creates a retrospective voice that adds maturity and self-awareness, both things that Liam lacked until he learned them in space.
