When seventeen-year-old Ax Novem wakes up in a strange, towering concrete skyscraper half-submerged in murky blue water, she has no memory of her past life except for fragments of basic knowledge and haunting visions. With only her name and an inexplicable sense of purpose, Ax finds herself thrust into a labyrinth of alternate dimensions known as the Tiles. Each Tile defies the rules of reality she once knew, presenting landscapes where gravity bends, time loops, and the impossible becomes the norm. Ax must master the art of survival in worlds where the only constant is change, and where her forgotten past may hold the key to saving, or destroying, them all.
