“Much like fine wine, battle-hardened assassins grow better with age.”—#1 New York Times bestselling author Lisa Gardner

Four women assassins, senior in status—and in age—sharpen their knives for another bloody good adventure in this riotous follow-up to the New York Times bestselling sensation Killers of a Certain Age.

After more than a year of laying low, Billie, Helen, Mary Alice, and Natalie are called back into action. They have enjoyed their time off, but the lack of excitement is starting to chafe: a professional killer can only take so many watercolor classes and yoga sessions without itching to strangle someone...literally. When they receive a summons from the head of the elite assassin organization known as the Museum, they are ready tackle the greatest challenge of their careers.

Someone on the inside has compiled a list of important kills committed by Museum agents, connected to a single, shadowy figure, an Eastern European gangster with an iron fist, some serious criminal ambition, and a tendency to kill first and ask questions later. This new nemesis is murdering agents who got in the way of their power hungry plans and the aging quartet of killers is next.

Together the foursome embark on a wild ride across the globe on the double mission of rooting out the Museum’s mole and hunting down the gangster who seems to know their next move before they make it. Their enemy is unlike any they’ve faced before, and it will take all their killer experience to get out of this mission alive.

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.
