Everything seems to be going wrong for Kyla. Her sister Olivia has been missing for years and the police are completely stumped. Her foster parents are struggling to continue with their lives, and her friends are starting to move into their own futures. She doesn't even know what to do. Then she meets Willow, a girl who has problems of her own. Willow has a weak body that can't do much exercise besides walking around. Willow's heart is strong, though. She is on a journey entirely different than Kyla's, but the two begin to walk side by side. And it changes everything.
