The Revenge of Rita Marsh : 'I devoured it.' Chris Whitaker

Summary: Rita Marsh is a good woman. By day, she's an ordinary small business owner running her late parents' care home, working gently with the elderly and infirm. By night, she's a vigilante, posing as young girls online. She snares the men who prey on them, exposing them for what they are. She's a force for good in a country whose justice system is crumbling. Rita has successfully kept her two lives separate for years, but when an old classmate returns from her past to tell her a years-old secret, her two worlds start to collide. With both of her selves unravelling, Rita will have to choose between justice and vengeance. Will she remain a protector - or become someone to fear?
