Angel's Glory (The Empress of Mysth #4)

Forbidden. Sworn Enemy. Wicked Seduction.
Savage angels have turned Earth into their hunting ground. To save all earthborns, the fey princess Rose cedes to the marriage demands of the King of Angels, knowing she won't survive the wedding night. When she comes to Atlantis to find a secret weapon to banish angels from our planet, she awakens the darkest lust in the king's lethal brother.
The most formidable angel comes across the universe and finds her. He will stop at nothing to possess her, even if he must fall.
The High Prince offers Rose an indecent proposal: sleep with him once and he'll keep her safe. Rose will turn his urge against him and destroy the angels' house. While unbridled lust burns the prince, it also torments her.
