Villains Academy (en Inglés) - M. K. Gibson

They tried to kill him. They tried to destroy his marriage. They tried to take his friends, his company, and his title, but did they succeed?! Well, yes... yes, they did. But that doesn't matter! For Jackson Blackwell, the one and only Shadow Master, took it all back. However, Sophia and her cabal of conspirators have gone too far this time.

Hidden deep within the Titan of Possibility exists the Sablestone Academy for Villains, the multiverse's premier educational institution in the nefarious arts. And it is here that the stakes have never been higher. The wager is simple: whoever has the best grades at the end of the school year may leave. The loser remains, trapped within Possibility for all time.

VILLAINS ACADEMY is the sixth adventure in the award-winning Shadow Master saga. To defeat his enemies and save his daughter, Jackson and his loyal crew of misfits must venture into the dark, soulless depths of genre fiction's red-headed stepchild... Young Adult Fantasy.
