Ripped is a wild journey back and forth in time, with humor and terror wrapped up in a mystery that is unsolved to this day. I loved the tone, told by a 15-year-old girl named Katie, whose sister is a rock star that looks just like her ancestor, a victim of Jack the Ripper. Throw in an education in both Cockney slang and 19th Century London, and you'll be glued to the pages, as was I. Careful attention to accurate details and occasional allusions to current pop culture keep this story realistic and interesting. As an English/Language Arts teacher of eighth graders, I recommend it to avid readers.
