Charming His Wary Vampire by Charlie Richards

Holden has watched as many of the gargoyles in his clutch have found their mates. His hope that his own mate will turn up begins to wane when years pass, and no new mates are found by the remaining single members of the Falias clutch. He begins to despair that Fate has moved her gift of mates to another clutch.
When a fellow gargoyle’s mother becomes gravely ill, the chieftain of another clutch—Chieftain Kinsey, who is also her son—comes to pay his respects. Holden is pleasantly shocked to find, amidst all the grief, there’s a ray of happiness. One of the men in Chieftain Kinsey’s entourage is his mate. He learns the man’s name is Lathe, and he’s a vampire.
Except, Holden discovers that scenting Lathe and wooing him are two very different things.
