Demon’s Mercy by Rebecca Zanetti

Duty meets desire . . .
Mercy O’Malley hates killing people. So when she’s assigned to take out Vampire-Demon Logan Kyllwood, she lures him to a seedy bar in Scotland, then decides to kidnap him instead. How can she cold-bloodedly end all that heat, those green eyes, that ripped body?
Unfortunately for Mercy, attempted murder and kidnapping are just foreplay for the Kyllwood brothers. Logan may be the youngest of the bunch, but death and violence are already a way of life. Now he’s ready to complete a painful, terrifying ritual to become one of the Seven, dedicated to protecting this world from the most dangerous evil it’s ever known. But first he has to deal with a blackmailing Fey, a ransom demand and his own pounding need for the last female he ever should have fallen for . . .
