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 60 years old, four women friends can’t just retire—it’s kill or be killed in this action-packed thriller by New York Times best-selling and Edgar Award-nominated author Deanna Raybourn.

Billie, Mary Alice, Helen, and Natalie have worked for the Museum, an elite network of assassins, for 40 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.

An isolated mansion. A chillingly charismatic aristocrat. And a brave socialite drawn to expose their treacherous secrets…. From the author of Gods of Jade and Shadow comes “a terrifying twist on classic gothic horror” (Kirkus Reviews) set in glamorous 1950s Mexico.

After receiving a frantic letter from her newly wed cousin begging for someone to save her from a mysterious doom, Noemí Taboada heads to High Place, a distant house in the Mexican countryside. She’s not sure what she will find – her cousin’s husband, a handsome Englishman, is a stranger, and Noemí knows little about the region.

Noemí is also an unlikely rescuer: She’s a glamorous debutante, and her chic gowns and perfect red lipstick are more suited for cocktail parties than amateur sleuthing. But she’s also tough and smart, with an indomitable will, and she is not afraid: Not of her cousin’s new husband, who is both menacing and alluring; not of his father, the ancient patriarch who seems to be fascinated by Noemí; and not even of the house itself, which begins to invade Noemi’s dreams with visions of blood and doom.

Her only ally in this inhospitable abode is the family’s youngest son. Shy and gentle, he seems to want to help Noemí but might also be hiding dark knowledge of his family’s past. For there are many secrets behind the walls of High Place. The family’s once colossal wealth and faded mining empire kept them from prying eyes, but as Noemí digs deeper she unearths stories of violence and madness.

And Noemí, mesmerized by the terrifying yet seductive world of High Place, may soon find it impossible to ever leave this enigmatic house behind.
