Found by Lisa Oliver

Raphael, Archangel of Healing, went about finding the demon mate he was intended for with the same dedication, focus, and purpose he did for anything else. If he was quietly annoyed that he wasn’t just given a name and told to get on with it, he didn’t mention it often, although he found the dates themselves mentally exhausting. He was almost glad a catastrophe of epic proportions came along to take his mind off his dating problems.
Seir didn’t expect to have an angel mate of his own. It’s not like he needed one, and from what he’d observed with Haures and Uriel, angel mates could be high maintenance. However, when Raphael asked him out on a date, Lucifer told Seir to say yes, so he did. After being bored out of his mind and then pretty much dumped at the end of the angel’s allocated time span, Seir never expected to hear from the angel again.
But remember that catastrophe? It appeared Seir was the one demon who might be able to solve the puzzle, but that meant Raphael and Seir working together. Could there be more between them than one disastrous date suggested?
