Ari Rosenberg dreams about a special room, one that shouldn't exist, and certainly not in his house. But when he wakes, he finds the room is real, and it's the doorway to another world. In that mysterious space, he meets Kimi, a visitor with his own door into the shared room. After a rough start, they forge a friendship that sparks with attraction and turns to romance, leading them to try to find a way out together, into one time or the other.
