Blue Twilight. Wings In the Night, #8

Strong sexual contentWomen are vanishing and the quiet town of Endover seems to be under a thrall... because it is. A  powerful and ancient vampire, possibly the very first of his kind, has taken the town over, and his victims have no one to turn to for help. No one, that is, except for Maxine Stuart. Mad Max has been digging into conspiracy theories about the undead since her teens, and now she has two secret weapons--the cop she adores and is determined to bed despite his resistance, Lou Malone, and her best friend Tempest "Stormy" Jones. Once in Endover, however, Stormy falls victim to inexplicable visions and odd fugue states, and it soon becomes apparent that this entire vampiric attack has been little more than performance art designed to get the three of them right where the vampire wants them.
And they have no idea why. Lou's an ordinary mortal man. His ability to resist Maxie's allure is as doomed to fail as his efforts to protect her and Stormy from the most dangerous vampire of them all.  And yet, he will try. even if it kills him.
