A Bend in the Road by Nicholas Sparks

Miles Ryan's life seemed to end the day his wife was killed in a hit-and-run accident two years ago. Missy had been his first love, and Miles fervently believes she will be his last. As a deputy sheriff in the North Carolina town of New Bern, Miles Ryan not only grieves for Missy, but longs to bring the unknown driver to justice...

Cold Wind

C.J. Box - Cold Wind

When Earl Alden is found dead, dangling from a wind turbine, it's his wife, Missy, who is arrested. Unfortunately for Joe Pickett, Missy is his mother-in- law, a woman he dislikes heartily, and now he doesn't know what to do-especially when the early signs point to her being guilty as sin.
But then things happen to make Joe wonder: Is Earl's death what it appears to be? Is Missy being set up? He has the county DA and sheriff on one side, his wife on the other, his estranged friend Nate on a lethal mission of his own, and some powerful interests breathing down his neck. Whichever way this goes...it's not going to be good.
