After spending years in prison for a crime she didn't intend to commit, Rose Collins is suddenly free. Someone who knows about the good work she has done--training therapy dogs while serving time--has arranged for her early release. This mysterious benefactor has even set her up with a job in the coastal Massachusetts community of Gloucester, on the edge of Dogtown, a place of legend and, for the first time since Rosie's whole world came crashing down, hope. There she works to rebuild her life with the help of Shadow, a stray dog who appears one rainy night and refuses to leave Rose's side. Meghan Custer is a wheelchair-bound war veteran who used to be hopeless, too. Living at home with her devoted but stifling parents felt a lot like being in prison, in fact. But ever since she was matched with a service dog named Shark, who was trained in a puppy-to-prisoner rehabilitation program, Meghan has a brand new outlook. Finally, she can live on her own. Go to work. And maybe, with Shark by her side, even find love again.
