"In the summer before her first year of middle school, word-chanting, rope-skipping Phee skips her way to imagined fame, writes down her innermost secret thoughts from the safety of a treehouse, and imagines in horror that her new classmates will eat her alive. Suddenly, her well-worn alley world feels too small. So when Mercy Jones moves next door, along with Mercy's skateboard and her don't-mess-with-me attitude, Phee sees the chance for her universe to expand. Even if it means leaving some things behind . . . It is a time of dares, of a legendary dog named Bull, of stretching comfort zones, and of old friendships made over in new ways. And it all takes place over the course of one alley summer."--Publisher's description.
