From the moment I met Nathan, a widower with two small children, I knew I would do anything for him. Sam and Sienna were both desperate for a mother and I knew I was perfect for them. I would raise them as my own, love them like my own. I would die for them. So when a missing teenager is found lying on the side of the road, my first through is for my precious kids. Are they home? Are they safe?

When I first walked into Jake and Megan’s immaculate home, I felt totally at ease. Sitting in the crisp white living room, they held hands and talked lovingly about their baby girl, Fern. As the weeks passed, I began to think I’d made a mistake in taking the job.

Who would do this to her? And why?

It’s time everyone found out about the secrets and about the threat that loomed over our marriage. It’s time everyone found out who really killed James.
