Redemption in blood

"Vesper Hyde is a model Penitent. Solitary. Skilled. Deadly. Only once has she ever lost a target, even though it almost cost her life. Now the one that got away is back with a vengeance, and this time he's determined to finish the job. She needs to overcome the whispers of doubt and let her instinct and training take over to redeem her failure. But on this second time around, she doesn't expect a sidekick. A very sexy, stubborn, human sidekick. Homicide Detective Decker Price has seen it all, including the murder of his wife at the hands of a twisted serial killer. When another murder pitches him headfirst into a world of vampires, witches, and sorcery, he is given a chance to mend shattered parts of his soul. But Vesper's world is as dark and alluring as the Penitent herself and he will come fact to face with echoes of his past in order to help her keep a vicious enemy at bay. If they are to succeed, they will need to push aside both their failings and work together to ensure the balance of their worlds remains unchanged. Redemption comes at a cost--is their love worth the price?"--Page [4] of cover.
