Eighteen-year-old Mark Hawthorne is finishing his final year of high school, living quietly in the background—an introverted art student who prefers sketching to speaking, and calm corners to crowded rooms. But everything changes the day he receives a simple sketchbook from his grandfather. The moment Mark draws inside it, he discovers an impossible truth: his art can come to life.

What begins as a private wonder quickly spirals into something far darker. Mysterious figures take an unusual interest in Mark’s newfound ability—most notably his new art teacher, Imogen Stone, whose charm and brilliance hide intentions Mark can’t decipher. As he’s drawn deeper into her world, he finds himself standing on the border between creation and control, beauty and danger, truth and illusion.

When his drawings start altering reality in ways he can’t fully understand—or undo—Mark is forced to confront a frightening question:
What happens when your imagination stops obeying you?
