The Dark Academy

They faced the mad headmaster,

a machine that took them to a post-apocalyptic nightmare,

a gang of superpowered criminals,

and a traitor from within their own group of friends.

But now Brendan and his allies must face a rival school in a conflict that may turn Dutchman Springs Academy into a war zone.
Meanwhile, his father is still missing, and possibly in the hands of his double from Not-Earth. Brendan isn’t the only one looking. A ruthless FBI agent is on the case, and he’ll stop at nothing to get Brendan to reveal everything he knows about the double, his supervillain father, and any otherworldly technology they might possess.

Brendan will have to turn to his friends. But it’s Lucille Bowman who may be the only one with the power to help, and she demands a price for cooperation. 

The Dark Academy is Book four of Supervillain High, an action-packed young adult science fiction series. In a world where becoming a superhero or supervillain is a global craze, Brendan and his friends embark on a new adventure that will challenge their strength and loyalty and test their understanding of what it means to be a true hero.
