Savvy is such a good book. I read it and listened to the audio tape version. It is about a girl named Mibs, who soon discovers her secret power, or "Savvy", on her thirteenth birthday. She goes on a whole crazy adventure with a boy named Samson and another boy named Fish. After hearing something quite devastating happening to their dad, they set out on an adventure to save him. With a bus driver by their side, they're determined to save him. I recommend this book to anyone who wants to read a book with a twist. I loved it!
