"Former Army Ranger turned government assassin Álvaro Montero and CIA Officer Caiden Cardosa crossed paths two years ago in Vienna, where their encounter ended less than amicably--despite the explosive sexual chemistry between them. Now Caiden is riding a desk at Langley after his cover is blown. And Álvaro--who was "killed"--has a new identity and purpose as Delta/D, an operative for the Locke and Keyes Agency, under the leadership of the mysterious Alpha Orion. When D and Caiden team up in a deadly black ops mission, the urge to kill each other will have to take a back seat to the desire for revenge against the man who betrayed them both. Surviving the mission won't be easy. Resisting the passion between them--that might be impossible."--Page 4 of cover.
