The Promise

Casey Kelleher

Two sisters. One murder. And an unbreakable bond.


Growing up in squalor with their drug-addicted prostitute mother, sisters Georgie and Marnie Parker have had to endure the very darkest side of life.

When their mother is sentenced for brutally murdering a client, Georgie and Marnie’s already precarious lives are blown apart and they now share a terrible secret. Sent to a children’s home, the sisters hope this might finally be their safe haven after years of neglect. But they soon discover they’re in real danger.

Desperate to find a place of safety, Georgie and Marnie run for their lives, but end up in the hands of Delray Anderton. A violent London gangster and notorious pimp, Delray has big plans for beautiful teenager Georgie, seeing her as a chance to make some serious money.

Fiercely protective of each other, Georgie and Marnie must escape the clutches of a man who will do anything to keep the sisters for himself. And, they must keep the promise they made to each other – no one can ever know the truth.

A gritty, shocking and gripping thriller that will engross fans of Kimberly Chambers, Martina Cole and Jessie Keane.
