Scholomance

"At the Scholomance, El, Orion, and the other students are faced with their final year--and the looming specter of matriculation, a deadly ritual that leaves few students alive after. El is determined that her group will make it out alive, but it is a prospect that is looking harder by the day as the savagery of the school ramps up. Until El realizes that sometimes winning the game means throwing out all the rules"--Provided by publisher.

"In the start of a . . . series, the . . . author . . . introduces you to a school for the magically gifted where failure means certain death--until one girl begins to unlock its many secrets. Enter a school of magic unlike any you have ever encountered: There are no teachers, no holidays, and no friendships save strategic ones. Survival is more important than any letter grade, for the school won't allow its students to leave until they graduate--or die. The rules are deceptively simple: Don't walk the halls alone. And beware of the monsters who lurk everywhere. El is uniquely prepared for the school's dangers. She may be without allies, but she possesses a dark power strong enough to level mountains and wipe out untold millions. It would be easy enough for El to defeat the monsters that prowl the school. The problem? Her powerful dark magic might also kill all the other students. So El is trying her hardest not to use her power--at least not until she has no other option"--Provided by publisher.
