When the book finally published in March 2026, they broke from their usual professional restraint to say publicly what this one had cost them. The release day letter acknowledged years of pressure between a first rough idea and the finished book, and then named the specific thing that made this project unlike everything before it.
Any time you do something different as a writer, you take a risk. And this one is different. It’s an entirely new world, completely unlike our own reality.
Five years before that letter, in a 2021 interview tied to the release of Blood Heir, a journalist asked each of them which genre they most wanted to explore. Gordon answered directly. Ilona’s reply was a closed door, with a reason behind it.
Gordon Andrews: “For me, epic fantasy or alternative historical fiction.” Ilona Andrews: “I am not going to comment because we have a future project in the works that I am very reluctant to discuss.”
The premise of the book, a reader dropped into the grimdark world of her favorite fantasy series, is the most literal form a certain working principle could take. Gordon stated that principle in a 2017 Goodreads Q&A, and it has organized every series they’ve built.
Write the book that you want to read.
A story built around a woman who has memorized every rule of a fictional world she loves is, in that light, less a departure than an extension of what they have always done.
Describing the Maggie the Undying trilogy on their official site, they named both the premise and the thing that makes it immediately, darkly funny: the world Maggie lands in is not a forgiving one.
Maggie The Undying is our new series coming from Tor. It is a trilogy that features Maggie, a reader who is transported into the world of her favorite fantasy series. Sadly, they were not the cozy kind.
The book’s central formal bet is that a reader transported into a fantasy world should encounter characters who feel like the platonic versions of their types. The release day letter explains what they built toward that end and what they were trying to capture.
We filled it with fantastic creatures, strange magic, and archetypes: the Golden Knight, the Noble Assassin, the Fire Mage, the Mad King. The side characters are heroes of their own stories. We wanted to condense the essence of what makes fantasy books… well, fantasy.
For a book whose premise depends on a reader recognizing those around her as if they were old friends, that choice is structural. The archetypes have to register immediately, or the emotional logic of Maggie’s situation collapses.
The mechanical process behind every book they have written is a genuine collaboration that runs at the sentence level, not just at the outline stage. They have described the arrangement consistently across multiple interviews, including this 2021 account.
We write together, meaning that one of us is at the keyboard and the other one is dictating. So everything that goes into the file is a compromise. Gordon has the final say over male characters. I have the final say over female ones.
Before Book 1 had been in readers’ hands for long, they were already deep into drafting its sequel. Their blog post answering reader questions after the March 2026 release gave a concrete sense of pace.
We are putting in over 2,000 words on This Kingdom #2 every day.
That output, sustained while fielding reader questions about a book just published, points to how far ahead their planning had extended by the time Maggie reached readers.
The romantic elements in their books arrive the same way the genre choice does: not from market calculation but from following their own reading instincts. They have made this point about their career-long approach, including in the First Coast News interview.
We didn’t actually sit down and say, ‘we’re going to write a romance.’ We just wrote whatever we wanted to read and it ended up being a romance. [paraphrased from audio]
In a 2012 guest post for The Book Smugglers, written when they were more than a decade away from Maggie, they described the test any female character has to pass in their work. They were writing about Andrea from the Kate Daniels series, but the standard they named is not series-specific.
She has a personal code of ethics. She has integrity and compassion and strives to do what she feels is right rather than what is easy, and in my opinion that’s what makes a character, male or female, truly tough.
The release day letter for This Kingdom Will Not Kill Me dropped the professional distance they usually maintain and acknowledged what the years between conception and publication had actually felt like.
You know we don’t do feelings, because we are professionals and all that, but this release is unlike any other we’ve had. So much time has passed between the first clumsy idea of Maggie and today, filled with work, pressure, and sheer effort. It doesn’t seem real.
That admission, from writers who have published more than a dozen books across fifteen-plus years, signals that Maggie was something they were carrying for a long time before it became a book.
The statement of intent in the release day letter makes no argument and advances no thesis. It names the single thing they were trying to give back to readers.
It is our sincerest hope that it reminds you of why you love fantastic worlds and the strange people who inhabit them.
On the series page of their official site, after laying out the grimdark stakes Maggie lands in, they closed with a line that sits in deliberate contrast to everything hard about the premise.
It was so fun to write, and we’re so excited to bring it to you.
That contrast, between a world designed to be punishing and the pleasure they took in building it, is probably the most honest summary of what they were after. The darkness in Maggie’s world is real, and so is the joy of being inside it.
