An unforgettable novel about the power of friendship and kindness by the New York Times bestselling author of Pay It Forward.

In the summer of 1969, fourteen-year-old Lucas Painter carries a huge weight on his shoulders. His brother is fighting in Vietnam. His embattled parents are locked in a never-ending war. And his best friend, Connor, is struggling with his own family issues. To find relief from the chaos, Lucas takes long, meandering walks, and one day he veers into the woods.

There he discovers an isolated cabin and two huge dogs. Frightened, he runs. And the dogs run with him. Lucas finds unusual peace in running with the dogs, and eventually he meets their owner, Zoe Dinsmore. Closed off and haunted by a tragic past, Zoe has given up. She doesn't want to be saved. She wants out. But Lucas doesn't want her to go, and he sees an opportunity to bring more than one friend back into the light. It's either the best or worst idea he's ever had, but Lucas isn't giving up on Zoe or Connor.

Their unexpected connection might be the saving grace that Zoe thought she'd lost, that Connor needs, and that Lucas has been running toward.
