Book 1 in the Casey Grimes series-where an invisible kid trains to fight monsters in the suburbs.
Being invisible sounds cool...until no one saves you a seat at lunch.
Casey Grimes isn't just ignored. He's actually invisible.
Kids walk into him. Teachers forget he exists. It'd almost be a joke...if it wasn't his actual life.
Everything changes when Casey climbs a giant oak tree after another humiliating day-and discovers a hidden fortress, a monster-haunted wilderness, and kids who treat battling beasts like gym class.
Suddenly, he's no longer the weird invisible kid-he's a kid who might accidentally die.
Because this isn't some cozy magical academy. This is a secret monster-hunting school. And America's backyards are the battleground.
Good news? Casey's tough, funny, and hard to kill.
Bad news? Everyone else is, too.
And his fearless little sister, Gloria, insists on tagging along. Together, they're thrown into a world of mythical creature attacks, suspicious teachers, and forgotten magic. Also...no bathroom breaks.
The monsters are real. The training is deadly. And Casey Grimes is in way over his head.
Suit up. Climb the tree. Face the monsters.
