** From the author of Stargazer, one of Cosmopolitan's hottest new beach reads for summer 2022, comes a sharp, disquieting thriller with a devastating twist **

Two sisters. One fire. A secret that won't burn out.

The Grayson sisters are trouble. Everyone in their small town knows it. But no-one can know of the secret that binds them together.

Hattie is the light. Penny is the darkness. Together, they have balance.

But one night the balance is toppled. A match is struck. A fire is started. A cruel husband is killed. The potential for a new life flickers in the fire's embers, but resentment, guilt, and jealousy suffocate like smoke.

Their lives have been engulfed in flames - will they ever be able to put them out?

Steeped in intrigue and suspense, Sister of Mine is a powerhouse debut perfect for fans of psychological thrillers and domestic suspense such as Liane Moriarty's Big Little Lies and Shari Lapena's The Couple Next Door.

'A solid psychological study of the relationship between siblings [...] the tension arises as much from the careful peeling away of the two girls' characters as it does from the mystery itself' - DAILY MAIL

'A twisty, claustrophobic nail-biter' - ENTERTAINMENT WEEKLY

'Beautifully written, tense and real' - ANN CLEEVES
