A 43-year-old man dies, and awakens to find himself back as an 18-year-old again. He relives his life, changing his decisions and actions based on his foreknowledge -- and then dies again at age 43. Each time he reawakens, he makes different choices and takes a different path.

The author does a great job of preventing the narrative from being a continuous cycle of later, rinse, repeat -- and the main character experiences some real personal growth and gains some wisdom. I loved this book, and can see why it was an award winner.
