"Lisa Edwards wandered into a pet shop on Halloween, well aware that the last thing she needed was a dog. But when she laid eyes on Boo, the runt of an abandoned litter, something compelled her to make him her own. The dunce of obedience class with poor eyesight and a wobbly gait, Boo was the least likely of heroes. Yet with his unflappable spirit and boundless love, Boo has changed countless lives through his work as a therapy dog. He has helped a mute six-year-old to speak, coaxed movement from a paralyzed girl, and stirred life into a ninety-four-year-old nun with Alzheimer's. Ultimately, Boo gave Lisa the greatest gift of all - faith in herself."--Publisher's description.
