Riley. The shy new eighth grader who's really into anime and nerdy things like that. Artemis. The outgoing eighth grader who sees into people's minds. In an attempt to get to know the former better, Artemis Rivers looks into Riley's mind one day in class. Big mistake. She's now stuck in Riley's freak show of a mind, trapped, being led around by a small embodiment of Riley that has a crow that is constantly perched on his shoulder, eating his flesh. Sounds like great fun, right?
