They don't call him Jackpot for nothing.

Seventeen-year-old Jack always beats the odds... at least until now. When a werewolf tried to kill him ten years ago, vampires saved his life. At first he was grateful. Then he realized he couldn't go home to his brother, couldn't return to his old life. Humans can become vampires; vampires can't become mortal again, but somehow Jack gets lucky. Like a cat, he always lands on his feet. He wakes up one morning without fangs, and the sunlight doesn't set him on fire. This is it, his dream, only it's real this time. What could possibly go wrong?

Enter a pretty hunter with dark secrets, a brother who wants to stake him just to be on the safe side, and a psychotic werewolf. Now we have a party.
