Two years after her husband's death, Kelly believes her romantic life is done. Until she reconnects with her girlhood crush on social media, and as fate would have it, he lives across the street.  James is over the whole true-love thing. His grasping ex-wife tore that belief out of him, when she left him for a rich, old man. Then he finds out his first love moved to San Diego too, and their attraction burns as hot as ever.

What they don't know is that Fate didn't bring them together, the Guardian Angel Corps did, led by two unlikely Cupids, Kelly's late husband and Zane, a rough and tumble, 19th century cowboy. When a Fallen Angel decides to tear Kelly and James apart, cherubs and harps aren't going to cut it, and Zane's unique skills might be just what they need to get a second chance at their first love.
