Pippa Evans had been a teacher at Penbryn Hall for just one week when her body was found alongside evidence of a pill overdose. Going undercover at the private school, investigator Mallory Dawson senses something rotten behind the wealth and privilege. Someone is leaving her coded messages: but do they want to help or harm the case?
Mallory soon finds links to the Solstice Sisterhood: a religious cult that believed punishment was cleansing. When a pupil is savagely attacked on school grounds, there is suddenly no time to lose in finding the killer.
A taut and twisty crime thriller set in the wilds of West Wales, perfect for fans of Clare Mackintosh and Fiona Cummins
