It doesn't take long for Tara Brennan to realize that breaking into school to steal a goat is not a good idea. As punishment for her crimes, Tara's parents send her to the sleepy town of Willow Falls to stay with relatives she hardly knows, including her strange younger cousin Emily. Tara quickly learns that Emily isn't even remotely the strangest person in town. There's a boy who sings at the bottom of an empty pool, two best friends who use blackboards to communicate, and a girl who may or may not be dating the world's hottest teen movie star.

Due to another lapse in judgment, Tara finds herself beholden to perhaps the strangest person of all: Angelina D'Angelo. If Tara can't collect thirteen mysterious objects for the old woman in time for her thirteenth birthday, the consequences will be REALLY BAD. With a big dose of birthday magic, Tara's adventures take her and her new friends to places they never thought they'd find, some in the real world, and a lot deep inside themselves.
