Fourteen-year-old Matt Archer spends his days studying Algebra, hanging out with his best friend and crushing on the Goddess of Greenhill High, Ella Mitchell. To be honest, he thinks his life is pretty lame until he discovers something terrifying on a weekend camping trip at the local state park. Monsters are real. And living in his backyard. But that's not the half of it. After Matt is forced to kill a strange creature to save his uncle, he finds out that the weird knife he took from his uncle's bag has a secret, one that will change his life.
Not a bad story really well thought out, be nice to understand where the monsters came from but suppose that's what book 2 is for.
