One Bite Stand by Esme Wilde

An Underworld demigoddess on a temporary ticket topside, Tina Lee will do anything to remain in the human world, even agree to a one-night stand with a playboy vampire to help her dodge the reaper who’s come to escort her back to Hades. So when the Mystic Matchmakers offer to help make her relationship with her sexy undead protector something more permanent, she’s more than willing to give it a try.
Malcolm Forbes isn’t looking for love. He thinks he already has it all — wealth, a satisfying career, and four brothers who’ve had his back for centuries. What he doesn’t have is the perfect woman to share it all with. Convinced that’s exactly what he needs, his oldest brother and new bride stage an “accidental” meeting between him and a successful matchmaking agency.
The Mystic Matchmakers have loads of experience in thawing the coldest bachelors’ hearts, so they gleefully accept the challenge to find the perfect match for Malcolm. They discover he’s an easier mark than expected when he agrees — no questions asked — to help protect the hilarious and outspoken Tina Lee from her reaper.
Tina’s well-meaning best friend, Malcolm’s meddling brothers, and the matchmakers help Malcolm recognize his growing feelings for the smoking hot Tina Lee. Unfortunately, keeping her in his life is not as simple as taking a knee and putting a ring on her finger. He’ll have to face the deepest, darkest powers of Hades to save their relationship or risk losing her forever.
