Bone and his sister, Squirrel, are stray dogs born in a shed. Left mother-less as puppies, the two dogs survive together for a while, but are soon wrenched apart, and Bone must now go on, alone.

Charlie is a boy who has suffered a terrible loss. And, as he's healing with the help of his dog, another tragedy occurs.

All Henry has wanted is a dog of his own, and now that his best friend has moved away, his parents still won't let him.

Bone, Charlie, and Henry live very different lives, but their stories connect in surprising ways. Award-winning author Ann M. Martin has written a powerful, heartfelt novel that's perfect for anyone who has ever longed for a dog, or loved one.
