Don’t Let Him In by Lisa Jewell. She’s a terrific writer of domestic thrillers, and this is about Nina who’s mourning the death of her husband, Paddy, after he fell under a train. A year on she receives a gift and a note in the mail from a man who knew Paddy and is sending condolences – which develop into an ongoing relationship, but Nina’s daughter is deeply suspicious of this newcomer and starts digging around. Meanwhile, Martha lives in a nearby town where she runs a florist shop and has a baby, and a husband who travels extensively for work and spends long periods of time away from home. As these characters all connect, things turn explosive.

We Are All Guilty Here by Karin Slaughter. She’s best known for the series she wrote with the characters Sara Linton and Will Trent, but this is the start of a brand new series set in a small town in the state of Georgia where there are secrets and lies a plenty. Emmy Clifton is the Deputy Sheriff who  starts an investigation when two teenage girls disappear from a 4th of July fireworks display. Karin Slaughter writes great thrillers – there’s plenty of misdirection and twists and turns, all while reminding us that even small towns can house a lot of darkness.
