I have enjoyed reading all of Jodi Picoult's books and this one did not disappoint me. The story revolves around Luke Warren, a man who has studied wolves his entire life. In fact he lived with them in the deep forests of Canada, becoming part of the wolf pack, hunting, eating, and playing with the wolves. He learned what their gestures to each other meant and the order of the pack. When he finally returned to his wife, son, and daughter two years later he really was a changed man. His family suffered during his absence. His son Edward now eighteen suddenly left home and shortly thereafter Luke and his wife divorced. Cara, their eleven year old daughter initially lived with her mom, but after her mother remarried and had a set of twins, she left to live with Luke. Cara takes after her father in her love of the wolves that he raises and protects. She understands his love of each wolf and what each member means to the pack. Late one night, Luke and Cara become involved in a terrible automobile accident. Cara will recover in time but Luke's fate is not certain. What happens when the prodigal son returns and decisions need to be made regarding their father's future? Edward and Cara will have to learn to understand how important each of them is in regards to their family and work together to come to a decision.
