That Girl Will Never Be Mine by Jessica Lynch

Welcome to Hamlet.
Population: 194… for now.
Three years ago, death and murder followed a pair of outsiders into Hamlet on the heels of a rainstorm. It ended with one outsider dead, the beloved sheriff gunned down, and her deputy being accused of all crimes.
That was three years ago.
Now? Mason Walsh has found his way back to Hamlet. Looking for revenge on the man who framed him, and obsessed with the woman who got away, the ex-deputy will do anything to make sure that he gets what he deserves.
Starting with becoming the villain he was set up to be…
***
Three years ago, Tessa Sullivan found her happy-ever-after with Lucas De Angelis, the beloved small town doctor who gave up everything for her.
Her time in Hamlet might have changed her, but she was glad to leave—even though her new husband’s ties to the secluded nook meant that she had to return from time to time, to face both her past, her losses, and her demons. After all, her first husband was murdered during her initial stay, and she’s terrified that something might happen to Lucas now.
But it’s not Lucas De Angelis who is the next target.
It’s his younger sister, Maria.
On the cusp of her wedding to Sylvester Collins—the current sheriff of Hamlet—Maria goes missing, and a clue at the scene has Tessa worried that long held secrets might be at risk.
Because, three years ago, Tessa chose one man over two others… and now it’s time he learns that she’s only ever belonged to him.
