Loma Shade is a bird-like native of Meta, a distant planet with a lingering interest in the scraps of nostalgic Earth culture they've collected. Shade uses her boyfriend's position as a security guard at a museum of Earth objects to steal the Madness Vest. She uses this to (somehow) transmit her soul to Earth, where she inhabits the body of a 16 year old girl, Megan. Megan has been lying in a coma after nearly drowning at a wild party with her swim team. Only her boyfriend Wes is happy about her surprise recovery- the rest of the team, and even Megan's parents, fear and resent her. Shade struggles to understand life as an Earth high school student even as she struggles to resist the raw Madness that swirls from her transport, the Vest. This book is part of the larger Young Animals series from DC, but I read and enjoyed it as a stand-alone.
