The prosaic plot description currently hosted for this book doesn't even begin to do justice to it. There's nothing prosaic about it all. Told from the perspective of Sabrina, who is only just beginning to understand how she is different from others and why, it's a beautiful, deeply moving story. Well written, it flows effortlessly in spite of the complicated subject.
That doesn't mean it's an easy book. While it was an exciting and constantly engaging read, it isn't what I'd call a fun book. This is a pretty dark story, overall, and in many ways sadly realistic - we're not talking Benny & Joon (though that certainly had dark moments, too). There's not really laughter or many "warm cuddlies" here. There were parts where I was literally filled with dread for Sabrina, whose vulnerability is terrifying to observe. James deserves a lot of credit for making her fear and confusion come alive for readers, but organically, without slowing the story down.
This is a Young Adult novel, and while I am an adult (with an appreciation for the genre stretching back to before that was true), I think it will appeal to its audience. Emotionally, it speaks to the parts of readers that feel isolated and misunderstood, that are exploring the balance between conformity and individualism. It will also fire the imagination, as the world of schizophrenia is dramatically presented, and draw on the mind, with thought-provoking issues such as sexual exploitation of the mentally ill. It presents a nuanced world, in which it is not always our enemies but sometimes our best friends who hurt us, and where the institutions we rely on to protect us (parents, school, hospitals) need our assistance if they are to succeed.
For those parents who might be concerned, I do not think the book will be *too* dark for most readers. It is, ultimately, an empowering story, and the sexual elements are not lurid.
I recommend.
