Heir of Ashes by Jina S. Bazzar

Her power makes her dangerous. Her enemies make her lethal.

Roxanne Fosch is no stranger to pain, betrayal, and captivity. Hunted by scientists who view her extraordinary abilities as a threat, she has endured years of torment, surviving brutal experiments and relentless manipulation.
When a rare chance for escape presents itself, Roxanne jumps in—talons first. But as she flees, she realizes that more than just scientists are after her. Darker, more powerful forces have their sights set on her too.
Can she trust Logan, the mercenary whose help comes at the price of her worst fear coming to life? Running forever isn’t an option, but to claim her freedom, Roxanne must confront the demons within, and unravel the truth behind why so many powerful players want her.
Her past made her a target. Now, she must fight to claim her future and her freedom—no matter the cost.
