Catacombs (Academy of Ancients #1)

Not quite. Her upperclassman mentor Zachary sucks. He's hot, but he sucks at being a mentor. And a friend. And a person.

Her roommate's a paranormal, and the whole school is underground and a secret.
Know what else is bad? Briar learns she's a witch. And a rare type of witch, to boot.

It went from bad to worse—a picture of a sister she's never heard of appears at the school. A sister she knows nothing about.

And the rules seem hellbent on keeping Briar from learning the truth. And sometimes, it seems other forces would rather not see her alive.

Warning: This series will hook you! Violence can be found in this series of action-packed fantasy, with necromancers, summoners, and badass witches.
