Hale's Angel (The Risen Series Book 1)

Hale is a demon who has been forced to act as his dark master’s assassin for centuries. Now to earn his freedom, he must complete one last task. Powerful and ruthless, he’ll stop at nothing to carry out this deadly mission.
Cera is one of the fallen, as in fallen angels. Only a few of her kind are left in the mortal world because they’ve been hunted to extinction. When the wickedly handsome Hale shows up at the bar where she works, she feels an instant attraction.
What begins as a simple flirtation soon turns into a seduction that leaves both angel and demon craving complete surrender. Cera has reawakened Hale’s black heart, but will it be enough to save her life?
