Savvy by Ingrid Law

342 pages; Dial
Mibs Beaumont is about to turn 13, and she knows that this means she will receive her "savvy," supernatural power that she will need to learn to control in order to not create chaos and arouse suspicion. Before Mibs gets a chance to celebrate her birthday, her father is in a bad car accident and is unconscious in the hospital. Mibs is sure that her savvy (when she figures out what it is) will wake up her dad, so she heads off on a wild road trip in a pink bus with her brothers and the preacher's kids.
