Chapel Field by Paula Hillman

A psychological suspense about silence and its sinister effects on a family and a village from the author of Blackthorn Wood.
When Laurie Helm's mother dies, Laurie must return to the village where she grew up. It's a place she left twenty years ago, and she's hardly seen her mother since. With no siblings or other family, Laurie is left to sort out the house and estate, and to face some of the reasons she left Chapel Field in the first place.
Ed Diamond grew up in Chapel Field—but it hasn't been much of a life. After his father passed away, Ed was the last person left who could care for his disabled sister. But the villagers have their own opinions on that . . .
Laurie and Ed met when they were kids, and as a disillusioned teenager, she joined in with the systematic tormenting of the Diamond family under the guidance of her friend, charismatic Marcus Butcher—until one of his pranks went too far. Now, reunited as adults, Laurie and Ed have lingering feelings of hatred, guilt, and resentment stirring between them—while being inexplicably drawn to each other . . .
