Nightmare Academy Books in Order

Charlie Benjamin's nightmares open portals that release monsters into the world. At an academy for children with similar gifts, he learns to fight these creatures, but his unusually powerful abilities expose a threat from deep in the Netherworld that endangers his friends and family.

Powerful monsters called the Named force their way toward Earth, and the Guardian who might stop them is dying. Charlie and his academy friends seek a way to save him, venturing through a hydra's cave, the Bermuda Triangle, and a monster-infested zoo.

The Fifth, mother of all monsters, reaches Earth with the powerful Pinch as her ally. As enormous creatures devastate cities worldwide, Charlie Benjamin and his friends face their most dangerous battle, with humanity's survival depending on their ability to stop the invasion.
