Every day A wakes up in a different body, never the same body twice. Forced to live a life that's made up of other people's lives, until one day A meets Rhiannon...
It's an interesting version of a sci-fi theme completely ruined by undermining it for some insipid romance between two thoroughly unlikable jerks who cavalierly damage the lives that are unlucky enough to be in their way.
If you were hoping for a weighty rumination on the differences of gender, class, and race, you will find yourself with some sanctimonious Levithan vignettes that always take a back seat to the romance. Oftentimes with some really problematic juxtaposition. Such as A dealing with the harrowing struggle of someone who is clinically depressed and suicidal, but it is totally okay to hijack that body in the midst of an intervention to force a kiss on the girl you are trying to steal away from her boyfriend, right? Or condescend to a girl host who prioritizes makeup and her beauty with a really male-centric "oh you girls will need to learn that makeup won't always work" internal monologue. Or sneer at a fat person, because A is supposedly amorphously gendered and with no clear racial identity or any defining physical features, but definitely not fat!
This book is vile. It's vile because it takes a high concept and wastes the opportunity for real diversity to half-assed vignettes and token gestures. It's vile because the narration tries so hard to tell you what a nice guy A is, but it's a story where he keeps repeating the same mistakes and the collateral builds to either be left unknown or dismissed off-handedly. Mostly, it's vile because it preaches, it aims towards a lot of good intentions while not noticing the huge and horrendously awful implications left silent in each situation.
So if you're like me and you love the idea but find the pitfalls to be fury inducing and are wary of trying it? If you want this concept but handled in a better way, one that strips down the concept to a romance and makes both parties look a lot more like real human beings? Check this out instead:
It's not perfect, but I think it delivers what Levithan was trying to say better than his own book.
