Lone Wolf by Jodi Picoult
When Luke Warren is involved in a car accident which leaves him in a coma, his family are gathered together against the odds; they face an impossible dilemma.
His daughter Cara is praying for a miracle: she will fight everything and everyone to save her father's life.
His son Edward can't imagine that a man who once ran with wolves could ever be happy with a different life.
But Edward hasn't spoken to Luke for six years. How can he dare to speak on his father's behalf?
Somehow, they must choose:
Do they keep Luke alive?
Or do they let him go?
