Neverthorn by Shannon Mayer [Paperback]

Neverthorn follows Harlow Daygon, a former student of Neverthorn Academy who dropped out after her mother's death and has since been surviving as an enchanted-jewel thief.

Her life takes an unexpected turn when the academy summons her back to join House Phoenix, a group of eight magical misfits with rare and secret powers. They are being trained because a powerful dark wizard, Nocta, threatens both the magical and mortal worlds, and House Phoenix may be the only force capable of stopping him.

Back at Neverthorn, Harlow must confront her past—including Typhon, her former classmate and nemesis, who is now the professor responsible for helping her unlock her hidden abilities. As mysteries, murders, and secrets begin to unfold, Harlow suspects that the academy's professors are hiding dangerous truths. To save the world, she'll have to discover her true power before darkness consumes everything.
