The God of Alpha (Sky-Titans #1)

Forget what you know about werewolves; forget what you know about vampires because what you know about them is entirely false. Michael Gilliganson is an African-American young boy living in a small Georgia town in the late 1920s unaware that the town he lived in his entire life bore a 2000 year old secret. After befriending a girl who can transform into a werewolf by using a powerful device called The Badge of Alpha his life takes a dramatic turn when he faces the greatest danger to not only him....but to the very lives he treasures.
