Hunted

Hunter 'Wolfy' McNabb is your average teenage boy with less than average parents. They go out every night from 11:30 till early morning to their 'astronomy group'. His parents are fascinated by the moon. One day he wakes and his parents are no-where to be found. There are two notes on the kitchen table the one reads 'Dear Wolfy, We are not who you think we are. We have waited till the perfect moment to initiate the hunt. Tomorrow is the first blood-moon in over a century. Our kind will feast for the next hundred years. We are not your parents. We are were-wolves. We have waited till you are of age to feast. We are the predators and you are our prey. Better start running...'
Next thing he knows his world gets turned upside-down and he doesn't know who to trust. He has to make some allies while also making some enemies. Because in a world where the people you thought you trusted are your predators, you know you're being hunted.
