More Praise for The Younger Wife:

"[An] appealing domestic suspense novel from bestseller Hepworth [with a] fast-moving plot. This often funny and affecting outing should win Hepworth new fans."––Publishers Weekly

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

"A warped tale [that] boasts Jane Harper’s multilayered characters and Liane Moriarty’s wealthy suburban world saturated with lies and deceit. With each domestic thriller, best-selling Hepworth shines brighter and draws in more readers."––Booklist

Oh, I love a dysfunctional family drama! Hepworth does a great job again writing a story with well-developed characters and a fast moving plot. At first it might not seem like a new story- an older man is going to marry a much younger woman but what if the wife is still very much alive and all the women have a secret they are hiding? Stephen, a heart surgeon, is engaged to Heather, a woman the same age as his two adult daughters. Tully and Heather are not thrilled about this but they are making an effort to get to know Heather. The ex-wife is still very much alive but also has own secrets. You may be wondering why Stephen doesn't just divorce his wife and remarry. That is revealed pretty quickly. The chapters alternate between the three young women. I was drawn in immediately with their personalities and the short chapters kept me wanting to read more. Tully is quirky, Heather is the quiet, strong one and Heather's past makes her a vulnerable character. The reveals from each are interesting but I wouldn't call them suspenseful/thriller twists. I know there are a lot of differing opinions on the ending. I'm not sure what was different in the ARC version

3-3.5⭐️ I enjoyed this. Kind of on track with the rest of the books I’ve read by this author. A good, but lighter mystery.

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.
