When 15-year-old Margot and her three sisters arrive at Applecote Manor in June 1959, they expect a quiet English country summer. Instead, they find their aunt and uncle still reeling from the disappearance of their daughter, Audrey, five years before. When the summer takes a deadly turn, the girls must unite behind an unthinkable choice or find themselves torn apart forever. Fifty years later, Jesse is desperate to move her family out of their London home, and Applecote Manor seems to be the perfect solution. But Jesse finds herself increasingly isolated in their new sprawling home, at odds with her 15-year-old stepdaughter and haunted by the strange rumors that surround the manor.

Amber Alton knows that the hours pass differently at Black Rabbit Hall, her London family’s country estate, where no two clocks read the same. More than three decades later, Lorna is determined to be married within the grand, ivy-covered walls of Pencraw Hall, known as Black Rabbit Hall among the locals. But as she’s drawn deeper into the overgrown grounds, half-buried memories of her mother begin to surface. Lorna soon finds herself ensnared within the manor’s labyrinthine history, overcome with an insatiable need for answers about her own past and that of the once-happy family whose memory still haunts the estate.
