I wanted to like this book because it deals with manic depression, but it was unreadable to me. The sentences were choppy ("Subject verb. Subject verb. Subject verb.") without conveying any information beyond what the character was seeing at the time. Although I understand it's how one's brain works when it's overloaded with either manic or depressive thoughts, I felt like Zwiren could have more effectively conveyed these feelings through description.
I recommend _An Unquiet Mind_ by Kay Redfield Jamison instead.
