"Completely compulsive. Sally Hepworth delivers with this stay-up-late one-more-chapter gem."––Jane Harper, New York Times Bestselling Author

3.5 Stars Rounded up.

I thought it was a well written. Stephen, a older man who's current wife is suffering and deteriorating from dementia has married a much younger woman named Heather who, consequently, is the same age as his two daughters Rachel and Tully.

It's written with all three women's POV and Sally Hepworth did a great job at giving each woman a distinct personality as well as suffering from various forms illness from kleptomania, eating disorders, sexual and domestic abuse.

It is deeply engaging and I read the whole book in two days as it kept my interest. Why is Heather marrying Stephen so young, what is the root of all these women's problems. Hepworth did a great job in creating a well paced thriller.

The ending was...... Not good in my opinion. There seemed to be too much confusion in the end and we were not given a clear resolution. Or a "why?"

Highly impressed with this author. This book was a bit of a mystery in “who did it” - took me awhile to get into it but once I did, I was eager to put all the mystery pieces together.
