13 Gifts (Willow Falls #3) by Wendy Mass

Middle Grade - Ages 10-14

Wendy Mass turns to another magical 13!

When Tara, a self-proclaimed shrinking violet, steals the school mascot, a goat, in order to make some friends with the popular crowd and gets caught, she gets herself in a heap of trouble. In addition, her parents decide that instead of taking her on their summer trip to Madagascar to study the courtship rituals of the Bamboo Lemur, she must go stay with her aunt, uncle, and bratty cousin Emily St. Claire in Willow Falls. Tara thinks it's a good time to start over; she'll be turning 13 after all, so she might as well make the best of it and perhaps even attempt to break out of her shell (in a non-criminal manner). What Tara doesn't know is that this charmed town has something big in store for her on her 13th birthday. It's not a typical birthday. But then again, nothing is Willow Falls is exactly typical!
