This book centers around estranged siblings Libby, Lucy, and Henry and their friends Phin and Clemency. Back on the eighties, their parents are found dead in their beautiful English mansion. By all accounts, it looks like they had formed a cult and they’d committed suicide. Henry and Lucy were teenagers and disappeared, while Lucy was a baby – abandoned on the scene. Twenty five years later, Lucy has had her birthday and is set to inherit everything (the home is worth millions). Her birthday brings the family members out of the woodwork and a mystery unravels. It alternates between their (very creepy and disturbing) childhood and modern day.
