While investigating a drug tip in the woods not far from his home, Jack McCain, an undercover drug investigator hears what he believes at first to be a little puppy. As he gets closer to the sound, he sees a pair of little eyes peering out at him. When he gets even closer he sees it's a little male wolf pup, with cuts and scratches, and obviously very hungry. He tenderly picks up the little injured wolf pup and takes him home with him, nurses him back to health and names him Chain. As Chain grows he becomes Jack's best friend and later his valuable partner. Jack doesn't know Chain's origin when he finds him. However, Chain's origin not only changes Jack's life forever, but the lives of his family, and his best friend. Chain wins Jack's love and respect and later on his housekeeper Mattie's, and thousands of Americans, as he risks his life to save others. As you read this book you will grow to love and respect Chain too.
