Shout-Out: Otherbound by Corinne Duyvis

Nolan doesn't see darkness when he closes his eyes. Instead, he's transported into the mind of Amara, a girl living in a different world. Nolan's life in his small Arizona town is full of history tests, family tension, and laundry; his parents think he has epilepsy, judging from his frequent blackouts. Amara's world is full of magic and danger--she's a mute servant girl who's tasked with protecting a renegade princess. Nolan is only an observer in Amara's world--until he learns to control her. At first, Amara is terrified. Then, she's furious. But to keep the princess--and themselves--alive, they'll have to work together and discover the truth behind their connection.
