The Salt in the Sea by J. D. Rivers

A downtrodden ex-soldier.

After leaving the military, werewolf Victor is shunned in his civilian life. Money is tight, so when an ex-comrade offers him an easy job—getting a package from an island—he jumps at the chance.

A lost inn-owner.

When Selkie Thoma opens the door to a knocking patron, he wants to close it again immediately. Standing before him is Victor, his one-night stand from three years ago. The last thing Thoma wants is to have to explain why he left that night.

As Victor and Thoma cross paths unexpectedly, emotions flare anew. But Victor is only on the island for a week, and Thoma can’t face his past, the consequences of his decisions, or the resulting condemnation from his sea-going selkie family.

A dead body in a post office.

When a corpse is discovered, fingers throughout the community point at Victor. With time running out before justice is served, it’s on Thoma to find out the truth. Because on the island justice is deadly.
