Before Madeline's bike accident left her with a traumatic brain injury, she and her twin sister were inseparable. So were her parents. But now, Madeline's parents are divorced and Becky has become rebellious, angry, and sneaky. Even worse, she doesn't seem to want Madeline around anymore. At least Madeline knows she can always rely on the miniature therapy horses she visits every week. Justin is a senior and the president of his school's Best Buddies club. Before his sister with autism died, he used to take her to the barn to visit her beloved therapy horses. Now, with Madeline, he goes there to escape the gloom of his mother's grief at home and the pressures of his final year in high school. Together, Justin and Madeline help each other to reconnect with the important people in their lives - and with the lives that they thought they'd lost.
