When I met Mark, I knew I had to make him mine. Thoughtful and sensitive, Mark lived in the most breath-taking house I'd ever seen - all glass and perched on the clifftop, with mesmerizing views across the waves below. It was where his first wife had died tragically, but it would be our promising new start.

When our gorgeous daughter Lulu was born, our perfect life was complete. But then I started having accidents at home. A broken hand... a black eye... Mark's sister thought I was doing it for attention, but she had no idea how scared I was of who I had become.

If I told you what my life with Mark has turned into, I doubt you would believe it. But I need you to listen because you're the only hope Lulu and I have left. And if I can make you see the truth, then maybe there's a chance I can save my precious daughter...

A book so twisty you won't be able to put it down. From the four-million-copy bestselling author, And So It Begins is an absolutely gripping read for fans of The Girl on the Train and The Woman in the Window.
