A Vampire's Promise (Ellowyn Found Book 2) MM

Vampires rule and blood whores obey.

After Asa ran from the lover who betrayed him, he vowed revenge. Now, years later, a powerful vampire wants him to steal seven necklaces from the king of the Ellowyn—or murder him. When Asa discovers that the king is his long lost love, he stumbles into a web of secrets and dark power plays he might not escape, because Asa isn’t the only one who wants the king dead. 

A promise he made long ago is tearing Zev apart. He’s a false king, haunted by his past and despised by many of his own kind. When a new employee, who looks uncannily like his old love, appears at the royal manor, Zev thinks he’s found his fated one again. But this lookalike calls himself Emek and can’t hide his horror of vampires. Zev longs to woo him back, but the annual coven meeting and threats to his life demand his attention. Though he escapes a mysterious attack, one of the lesser princes isn’t so lucky, and all signs point to Asa as the killer.

Now with a murderer running loose and enemies surrounding him, Zev has one last chance to save his love.

But time is running out.
