Graduation Day (the Testing, #3)

The third and final installment in The Testing trilogy is set in the United Commonwealth, a nation rebuilt after the Seven Stages of War, a series of global conflicts that devastated civilization. The story follows Malencia "Cia" Vale, a student at the University in Tosu City, as she confronts the corrupt systems governing her society. In previous books, Cia survived The Testing, a brutal selection process for future leaders that kills many candidates, and discovered that the rebellion against The Testing's architect, Dr. Jedidiah Barnes, is itself a trap designed to identify and destroy his opponents.

The novel opens with fellow Government Studies student Raffe Jeffries warning Cia that Professor Holt, the head of their residence, knows they left campus, and that another student is searching for their classmate Damone, whom Cia killed in self-defense. Cia faces converging dangers: The rebellion led by Symon Dean is a sham orchestrated with Dr. Barnes to lure out dissenters; President Anneline Collindar's proposal to strip Dr. Barnes of power is expected to fail in the Debate Chamber, the Commonwealth's legislative body; and Cia's brother Zeen is embedded among the rebels. Using a Transit Communicator, a short-range communication device, Cia contacts Zeen and tells him that Symon killed their ally Michal Gallen, a Tosu City official, and destroyed the evidence Michal had gathered. Zeen agrees to stay and gather intelligence.

Desperate for help, Cia rides to the president's office. She is alarmed to see Symon emerging from the president's quarters. Once alone with Collindar, Cia reveals everything. The president believes her and will postpone the Debate Chamber vote by reporting Michal missing, buying up to a week. Then she reveals her true plan: Cia must assemble a team to eliminate Dr. Barnes and 11 of his top administrators. Collindar argues this is the only way to prevent open warfare and Dr. Barnes's consolidation of power. She provides files on each target, access to a room stocked with weapons and surveillance equipment, and adds Symon as a 12th name to the list.

Horrified but unable to dismiss the logic, Cia takes only radios, recorders, and tracking devices from the weapons room. She hides the files in an abandoned house and modifies the radios for secure communication. Over the following days, she builds her team. Tomas Endress, her love interest and fellow Five Lakes Colony student, pledges to fight beside her. Stacia, a pragmatic Medical studies friend, agrees immediately. To vet Raffe, Cia constructs a fake radio rigged with black powder: If he activates it, the device will explode, eliminating a potential traitor.

Raffe passes the test by leaving the device untouched, having deduced its purpose. He reveals his motivation: His sister Emilie was supposedly Redirected after failing the entrance exam, meaning assigned to a colony job, but his investigation proved she never arrived. He believes Redirected students are used as experimental subjects. Raffe questions several names on the president's list, arguing that at least five are opponents of Dr. Barnes rather than supporters. He believes only four people plus Symon need to be removed: Dr. Barnes, Professor Holt, Professor Chen, a University administrator who oversees candidate selection, and his own father, Official Rychard Jeffries.

Events accelerate when Tomas's inquiries about a former student draw the attention of rebel sympathizers on campus. Two rebel students ambush Cia and Tomas at the stadium. In the fight, Cia is grazed by a bullet. She and Tomas lure their attackers into a greenhouse and ignite toxic plants, killing both with the fumes. The situation worsens when Stacia, without authorization, redirects the rigged device to Enzo, another student. Enzo triggers the explosive in Cia's room and is severely burned.

The blast forces Cia to flee campus. Ian, her final-year guide and a rebel sympathizer, initially blocks her at gunpoint but relents when Cia reveals Symon's betrayal. She removes the tracking device from her University bracelet, retrieves additional weapons, and hides with Tomas in the abandoned house. They build timed explosives for diversions, and Tomas prepares plant-based remedies, including a lethal poison as a last resort. Zeen contacts Cia and agrees to kill Symon when the attack begins.

Raffe and Stacia arrive at the house, Stacia nursing a gunshot wound from rebel students. Will O'Donovan, a student who betrayed Cia during The Testing but intervened to save Raffe and Stacia, accompanies them. Despite her distrust, Cia accepts Will's help planting diversionary explosives, since officials are not searching for him. At dusk, after the first explosion, the team splits: Raffe and Cia target his father and Dr. Barnes, while Tomas and Stacia target Professor Chen and Professor Holt.

At his family home, Raffe interrogates his father, who confirms that Redirected students serve as conscious subjects in mutation experiments. Raffe shoots him. At Dr. Barnes's house, they discover Symon has set an ambush inside with armed men. Raffe stays to confront Symon while Cia continues alone to The Testing Center, hearing gunshots and an explosion behind her.

Inside, Cia finds Dr. Barnes in the interview room where she was once evaluated. A guard disarms her, but Dr. Barnes dismisses his guards and claims he has been facilitating her journey all along, monitoring her through a device hidden in her bag. He reveals that President Collindar does not want to end The Testing but to expand it, believing harsher selection is necessary as other nations begin making contact. Dr. Barnes drinks his own truth serum to prove his sincerity, places his gun in Cia's lap, and asks her to shoot him, saying his death will fulfill an agreement with the president to end The Testing.

Before Cia can decide, Symon bursts in with armed men, bloodied from the explosion. Dr. Barnes reveals that The Testing and the Redirection program are ending, then shoots Symon. Symon fires back. Tomas, Will, and Zeen arrive in the chaos. Symon, wounded on the ground, fires a final shot at Cia. Zeen throws himself in front of the bullet. Cia kills Symon, and Will fires the final shot. Zeen dies in Cia's arms, asking her to tell their parents he saved her.

President Collindar arrives and publicly blames Symon for all the violence, including Dr. Barnes's death. Privately, Will tells the president that Cia killed Dr. Barnes, deflecting credit from himself. Cia examines the body and recognizes three precise chest wounds as Will's marksmanship. She sips the remaining truth serum from Dr. Barnes's glass, confirming its authenticity and validating his claims about the president's true intentions.

In the weeks that follow, Cia recovers at the University, where Enzo is healing and Raffe, who survived the explosion, grows stronger. She accompanies the president to Decatur Colony and sees former candidates used as experimental subjects. She brings home Raffe's sister Emilie and Will's twin brother Gil, both with their colony memories erased. Collindar announces The Testing's end before the Debate Chamber. Cia returns to Five Lakes Colony, visits grave markers for Zeen and others, and tells her family the truth. Though Tomas is content to stay and Cia longs to remain, she decides she must return to Tosu City, resolved to watch over the country's leaders and ensure nothing like The Testing happens again. She puts her bracelet back on and walks toward Tomas, hoping he will choose to make the journey with her.
