A planet made entirely of doors. Maia, a sixteen year old girl, and Lio, her small white fluffy dog, wake up stranded on its endless surface, surrounded by thousands of doorways that open onto strange and impossible worlds. Every door promises an escape except the one that matters most, because none of them lead home. As Maia and Lio search for a way back, they start noticing the same battered door reappearing wherever they go, always a few steps behind them, its handle rattling from the inside as if something is clawing to get out. The deeper they explore, the more this planet feels less like a maze and more like a trap built specifically for the two of them, and time is running out to figure out why.
