Darling Girls by Sally Hepworth

Publisher's Synopsis

It's not just secrets buried at Wild Meadows.

For as long as they can remember, Jessica, Norah and Alicia have been told how lucky they are. Rescued from family tragedies and raised by a loving foster mother on an idyllic farming estate, they were given an elusive second chance of a happy family life.

But their childhood wasn't the fairy tale everyone thinks it was. And when a body is discovered under the home they grew up in, the foster sisters find themselves thrust into the spotlight as key witnesses. Or are they prime suspects?
