Lawless by Lisa Henry

Welcome to Dauntless Island. Unless you’re Senior Constable Dominic Miller.

When Dominic Miller gets the opportunity to run Dauntless Island’s first police station, he jumps at the chance. What could be better than community-based policing on a breathtakingly beautiful island? It turns out, everything. Because they don’t like outsiders on Dauntless Island, and they especially don’t like coppers.
Natty Harper needs a job, and offering to clear the new copper’s garden seems like a good way to earn some cash. Just as long as nobody finds out. And the new copper might be cute, but it’s not like Natty’s going to do anything stupid like fall for him, right?
Especially when Natty might have an illegal side gig going on.
It’s lucky Natty is descended from mutineers, because he and Dominic are about to break all the rules on Dauntless Island.

Lawless contains a bemused copper who wants to make friends, a Dauntless Islander who wants to get laid, an angry brother, a useless cousin, an actual emergency, and a sea cave. And also a cat called Frank.
