When Tara, a self-proclaimed shrinking violet, steals the school mascot—a goat—to make some friends with the popular crowd, she gets caught and lands in a heap of trouble. 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, so she might as well make the best of it and perhaps try 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 in Willow Falls is exactly typical!
Wendy Mass turns to another magical 13!
