Books like Nightmare Academy
Nightmare Academy: Monster Madness is the second book in the Nightmare Academy series by author Dean Lorey following the fictional events in the lives of characters Charlie Benjamin and his friends, Theodore Dagget and Violet Sweet, in their attempt to prevent the remaining Named from traveling back to Earth and summoning The Fifth.
The beginning of the novel takes place with Charlie and friends getting ready for their final exams in the hope of grading and becoming Addys. They are sent by Rex, Tabitha and Pinch to Bungalow C, a place in a rather droopy area owned by Dora [eight years old] and her father Barry. Dora is not old enough to train at the Nightmare Academy yet, and so has not been informed of her ability to portal in Nethercreatures through her Nightmares. Using a Gremlin Attracter, the three friends find and begin to Banish three Gremlins, but not before a Class 2 Darkling from under Dora's bed reaches out and eats them. Still not satisfied, it reaches out to take Theodore, but is only just stopped, saving the skinny boys life. Violet begins closing the portal to the first ring of the Nether she was going to Banish the gremlins with when a Class 4 Netherleaper, Rex calls them 'Dangeroos' captures Violet.
