Eleven-year-old Casey Grimes is invisible. Really. When he leaves suburbia and infiltrates a secret forest society, he can finally be seen—but Sylvan Woods hates outsiders as much as it loves killing monsters. As Butcher Beasts invade, his flimsy cover story falls apart, and courage is his only chance to belong. $0.99 on Kindle.
