West of Port by Carina Taylor

Sydney is out for revenge no matter what it takes—including teaming up with a grumpy, retired cop who wants nothing to do with her.
West has retired from the police force. Completely burnt out, he doesn’t want to protect anyone anymore. All he wants is to be left alone so that he can refinish his new-to-him sailboat.
Unfortunately for him, a woman shows up asking for his help—needing his help.
He does the only thing he can.
And says no.
But that doesn’t seem to stop her from seeking him out when her plans for revenge go sideways and she’s now the target. He can’t just walk away and leave her to fend for herself.
Now he’s stuck with a cheerful, optimistic, vengeance-bent woman as a passenger on his sailboat.
West might not have been able to keep her off his boat, but he’ll surely be able to keep her out of his heart.
Maybe.
