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?

peeling away of the two girls' characters as it does from the mystery itself' - Daily Mail

'A twisty, claustrophobic, nail-biter' - Entertainment Weekly
