Older women often feel invisible, but sometimes that’s their secret weapon. They’ve spent their lives as the deadliest assassins in a clandestine international organization, but now that they're sixty years old, four women friends can’t just retire—it’s kill or be killed in this action-packed thriller by New York Times bestselling and Edgar Award–nominated author Deanna Raybourn.

Billie, Mary Alice, Helen, and Natalie have worked for the Museum, an elite network of assassins, for forty years. Now their talents are considered old-school and no one appreciates what they have to offer in an age that relies more on technology than people skills.

When the foursome is sent on an all-expenses paid vacation to mark their retirement, they are targeted by one of their own. Only the Board, the top-level members of the Museum, can order the termination of field agents, and the women realize they’ve been marked for death.

Now to get out alive they have to turn against their own organization, relying on experience and each other to get the job done, knowing that working together is the secret to their survival. They’re about to teach the Board what it really means to be a woman—and a killer—of a certain age.

Killers of a Certain Age

The series

Full series details →

A lifetime spent in the shadows teaches you two things: how to disappear, and how to strike when no one is watching. In Killers of a Certain Age, four women who once served as elite assassins discover that retirement is not the safe haven they imagined. Instead of quiet days and freedom from violence, they are thrust into a fight for their lives against the very organization that trained them.

Read full series description

At the heart of the story is the bond between Billie, Mary Alice, Helen, and Natalie. Decades of shared missions have forged unshakable loyalty, but also left scars that resurface when the past refuses to stay buried. Their skills may be called old-fashioned in a world driven by surveillance and technology, yet it is precisely their experience, cunning, and ability to blend into invisibility that makes them unstoppable.

What sets the series apart is the balance between razor-edged suspense and the darkly funny recognition of what it means to age out of society’s spotlight. Action scenes bristle with energy, but they are grounded by the humor and humanity of women who understand that being underestimated can be its own kind of power.

Critically acclaimed and embraced by readers worldwide, the series has been celebrated for refreshing the thriller genre with characters who are as sharp, dangerous, and unforgettable as their younger counterparts. It is a tale of survival and reinvention, one that proves the deadliest players are often those no one thinks to notice.

What Risingshadow readers think about this book

6/10

This book was just ok.  I thought the characters were not developed early enough or in enough detail for me to be invested.  The main characters behaviors were inconsistent with what you would expect from seasoned assassins in their 60’s.  They behaved like teenagers which made the story less believable.  I also found the ending part of the story unbelievable.
