When widowed sisters, Hester and Harriet, move together into a comfortable cottage in a pretty English village, the only blights on their cosy landscape are their crushingly boring cousins, George and Isabelle, who are determined that the sisters will never want for company. Including Christmas Day.

On their reluctant drive over to Christmas dinner, the sisters come across a waif-like young girl, hiding with her baby in a disused bus shelter. Seizing upon the perfect excuse for returning to their own warm hearth, Hester and Harriet insist on bringing Daria and Milo home with them.

But with the knock at their front door the next day by a sinister stranger looking for a girl with a baby, followed quickly by their cousins' churlish fifteen-year-old son, Ben, who also appears to be seeking sanctuary, Hester and Harriet's carefully crafted peace and quiet quickly begins to fall apart.

With dark goings-on in the village, unlooked-for talents in Ben, and the deeper mysteries in Daria's story, Hester and Harriet find their lives turned upside down. And, perhaps, it's exactly what they need.
