Lone Wolf by Jodi Picoult

Luke Warren, a wolf biologist, suffers a traumatic brain injury from an accident while driving his daughter, Cara, home from a party where she had been drinking.  Luke, famous for his research on wolves, is comatose, on life support, and doctors say he will not recover. His son, Edward, though estranged from his father for six years, returns after receiving a call from his mother.  Luke always put wolves ahead of his family which caused the collapse of his marriage.  He did have a strong bond with his daughter, Cara.  Edward and Cara are at odds over which direction to take with their father.  Cara expects a miracle; Edward, based on what the doctors have told him, feels they should let their father go and donate his organs.  A legal battle begins.  This book deals with many hurts of the past in this family.  It also deals with a lot of wolf behavior and the comparisons between wolves and humans.  Though I didn't care for some of the characters and the ending involving another character was strange, I found the book interesting and emotional.
