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?
