Mason Wallace has always blended into the background. In his small coastal town tucked between the misty forests and storm-beaten shores of the Pacific Northwest, he's never been the star of anything - not in grades, not in sports, not even in looks. "Average" might as well be his middle name. But everything changes one fateful night in the woods when something - something not human-sinks its teeth into him.
Waking up different, Mason's life spins completely out of control. His senses are sharper, his strength is inhuman, and the reflection in the mirror doesn't quite look like him anymore. Now, he's forced to juggle the chaos of high school with the terrifying truth of what he's becoming.
As if that isn't enough, his best friend won't stop ranting about fantasy tropes and monster conspiracies, a mysterious stranger seems to know far too much about Mason's condition, and the new girl at school - the one Mason can't take his eyes off - is hiding dangerous secrets of her own.
Between unraveling his identity, keeping his transformation under wraps, and surviving the darkness creeping into his once-ordinary life, Mason is about to learn that being "average" was the last normal thing he'll ever be.
