This is based on the book Bad Kitty, by the same author. I never read it, but I believe it was one of the YALSA top ten teen books last year. Anyway, this was very cute. Jas is a girl next door type who just falls into mysteries to solve, this one being a jewelry store robbery. She has a crew of friends and a world-famous guy she is sort of seeing. Anyway, I really liked it, and it made me want to move Bad Kitty and its sequel Kitty Kitty further up on my reading list.
