Books like I Am the Wallpaper

This book has the generic feel of one written by someone who has never read a young adult novel and thinks: well, i'm writing about a thirteen year old girl, so there should be a diary, an embarassing incident involving a bra, a crush, a fight with her best friend, etc...But more troubling is how utterly unlikeable the narrator is. She has no qualms about stealing her best friend's crush, and frequently makes commments like, "Thank God Rebecca Greenblatt was such a fatty." The only moments in which she is sympathetic are those in which other people treat her poorly. She makes not one kind gesture, nor thinks one kind thought in the entire book.Add to that some weird plot bits like her flighty 21 year old sister dating many men in March, and then marrying one in June with no discussion of that being worrysome or surprising.Ugh.
