Rekindled Prophecy by KC Freeman

Defying Heaven and Hell, a guardian angel reignites a deadly prophecy.

All a guardian angel wants after 450 years of saving humans is a little rest. Too bad evil never takes a break. Greylyn’s vacation is over before it starts.
Kael, Hell’s most lethal weapon, awaits Greylyn at the cozy bed and breakfast nestled in the Shenandoah Mountains. They have battled each other for centuries, but neither has dealt the death blow.
A young bride in peril lures them both into the clutches of a notorious fallen archangel. Innocent lives hang in the balance. An unlikely alliance binds eternal enemies together in a quest to unravel a prophecy so deadly that Heaven refused to write it down.
