Bestselling author Elias Vayne has spent years writing stories to escape the horrors of his past. As a child, he was the sole survivor of a massacre that wiped out his entire orphanage. He doesn’t remember how he survived—only that when the slaughter ended, he was the only one left standing.His latest work, The Arcane Academy Chronicles, takes place in Veylin Academy, a prestigious school of magic and combat. But one night, after finishing the final chapter, Elias wakes up inside his own book—not as the hero, not as the villain, but as an extra. Worse, he’s been reborn as Kael, the very same orphan who survived a similar massacre in the story.But something is wrong. The academy isn’t as he wrote it. Characters are acting off-script, unknown forces are rewriting events, and the mystery surrounding Kael’s survival mirrors the one in Elias’s real life. The more he tries to regain control of the narrative, the more he realizes this world may not be his creation at all.
