Rafe's War — Jade James

The humans thought they had years before the foretold apocalypse would arrive. They were wrong... The angels and chosen humans are to unite, to save the world from endless destruction, resulting in a bonding that will last forever. Archangel Rafe's assignment is twofold; convince Melina to join him eternally, and to protect her against the evil that stalks her. Love was the last thing he was expecting to find.  Even with everything she's seen, Melina's not prepared when Rafe saves her. He claims she was destined to be his wife, but Melina can't accept that idea without his love.
