Query: Disappointing

This book is built on an intriguing concept, but the result is disappointingly dull. Seems like if you've read one teenage girl's diary, you've read them all--this one included. It's filled with entries on how much she hates school, hates her mother, boyfriend drama...relatively little of the book deals with her depression and self-injury. It does contain a lot of artwork, which provide a welcome respite from the pages of mundane details, but overall this book just doesn't work.
