I take a sip of coffee as I plan my day. My surgeon husband, Cole, slept at work last night, so I had to get the kids ready on my own, again. I can’t complain, though, I’ve loved him ever since we met, long before he became a famous surgeon and the papers started calling him the pride of the hospital.

My heart pounded with fear, but I plastered a smile on my face for the sake of my children.

Because Ellie’s always hated me, ever since she realised it was no longer just her and Theo. Now she’s seventeen, beautiful and smart–smart enough to see through me. And if Ellie decided to uncover my secrets, it wouldn’t be just my marriage at stake… it would be my life.
