A Warm Heart in Winter (Black Dagger Brotherhood #18.5) by J.R. Ward

In this romantic and sexy addition to the #1 New York Times bestselling Black Dagger Brotherhood series, a beloved couple has everything arranged… until it all goes horribly wrong.

Blay and Qhuinn always intended to do a proper mating ceremony, but life has a way of getting in the way. With a pair of young, responsibilities to the King, and a grueling fighting schedule, the two are exhausted and overwhelmed. When Qhuinn gives his male the proposal of a lifetime, however, they are excited for their special night and more in love than ever.

Everyone in the Black Dagger Brotherhood’s mansion gets into the preparations, and the after party takes on epic- and immortal- proportions when Lassiter forms the Party Planning Committee. The celebrations promise to be all that the couple deserves… until a Nor’easter land locks Caldwell in a fierce storm, and things go from lighthearted to deadly dangerous.

Battling nature and responding to emergencies, Blay and Qhuinn get separated, and when a catastrophic chain of events puts one of their lives in jeopardy, the night they had so looked forward could mean the end of everything…
