The Heir of Death (The Final Formula Series, Book 3.5)

Elysia Mallory has never embraced her magic, not when doing so comes at the price of her sanity. Her family is cursed with bizarre necromantic gifts that have driven each recipient mad, and she doesn't want to be another dead branch on the family tree.

But when Elysia learns that an ancestor is still in the mortal world and using his rare gift to possess the Deacon, the leader of the necromancer community, she decides it's time to take control of the power she was given. Will her gift give her the ability to right a wrong centuries in the making? Or will she become another puppet for him to control?
