'I was born two years into my mother's captivity. She was three weeks shy of seventeen. If I had known then what I do now, things would have been a lot different. I wouldn't have adored my father.' When notorious child abductor - known as The Marsh King - escapes from a maximum security prison, Helena immediately suspects that she and her two young daughters are in danger. No one, not even her husband, knows the truth about Helena's past: they don't know that she was born into captivity, that she had no contact with the outside world before the age of twelve - or that her father raised her to be a killer. And they don't know that The Marsh King can survive and hunt in the wilderness better than anyone ... except, perhaps his own daughter. Packed with gripping suspense and powerful storytelling, The Marsh King's Daughter is a one-more-page, read-in-one-sitting thriller that you'll remember for ever.
