The Grimm Legacy by Polly Shulman.
Summery: Elizabeth is a girl at a new school. She has hardly any friends and is excited when her social studies teacher recommends a job for her. At a sort of library he called it. But it has to be better than being friendless and nothing to do really. However it isn't a library with only books, as she soon learns. It has all sorts of things that Patrons can take out even Marie Antoinette's wig! But the most mysterious of the collections of items is the Grimm Collection. Everyone is whispering about it...and the giant bird that tried to attack the last page, an amazingly magical adventure awaits!
Romance:A few kisses (not very descriptive), liking someone, thinking/talking about someone, touching.
Violence:Giant bird attacking, fighting with a dog/griffin as well, yelling/arguments, almost being eaten/attacked by a rat, mean words/cursing someone.
Other:Magic, lying, stealing, breaking the rules, a little boy makes a picture when he relieves himself and is proud of the "sun" he made.
My Thoughts: A great fantasy book! Lots of magic, a touch of romance and some interesting and funny bantering thrown in as well. I truly did enjoy it and the characters were likable, if not lovable. Even though it was for middle school/tween readers I still liked it and it was still pretty mature (so 12 or 13 not tween as in 10). I would recommend to tweens about that age ^^ and mostly to girls.
