When human bones are found in the garden attached to the glamorous London home where she grew up, Jess McIntyre prepares to receive the news she has dreaded for thirty-four years: that her sister, Nina, is dead and now here is the proof. Nina disappeared without a trace in 1992, aged eighteen, the summer she fell in with a charismatic group of friends who squatted in a vacant house on the other side of Willow Gardens.

Having moved to Australia years ago, widow and single mum Jess arrives back in London to provide a DNA sample to help the investigation, with her teenage son, Ollie, in tow. As they try and unravel the secrets of Nina's past, and her connection to a sinister cult, will they discover that some bodies are best left buried.
