Lone Wolf by Jodi Picoult

A story of a man who is driven to share his life with wolves to the exclusion of his family, Picoult shares each character's story by chapters. The main character, Luke, is the "alpha male". Always comparing his human life, considered by him inadequate, to the life of a member of a wolf pack. Which in turn causes his family to deteriorate. His daughter, Cara, has chosen to live with her father when her mother marries again, and has twins, creating a "new" family. When Cara and Luke are involved in a terrible accident putting Luke in ICU with no chance of recovery, Cara wants to try everything she can to keep him alive. Cara's brother, Edward, left home at eighteen in a fit of pique at Luke. His mother has asked him to return to the states to Luke's bedside. Picoult weaves a tale of a human family and with life in a wolf pack, comparing the sameness and the differences, the responsibilities and the love or lack of it. A page-turner; a psychological puzzle as each character struggles to understand their place in this imperfect world.
