About The Book

The New York Times bestselling “new Agatha Christie” (Air Mail) Ruth Ware returns with this adrenaline-fueled thriller that combines Mr. and Mrs. Smith with The Fugitive about a woman in a race against time to clear her name and find her husband’s murderer.

Hired by companies to break into buildings and hack security systems, Jack and her husband, Gabe, are the best penetration specialists in the business. But after a routine assignment goes horribly wrong, Jack arrives home to find her husband dead. To add to her horror, the police are closing in on their suspect—her.

Suddenly on the run and quickly running out of options, Jack must decide who she can trust as she circles closer to the real killer in this unputdownable and heart-pounding mystery from an author whose “propulsive prose keeps readers on the hook and refuses to let anyone off until all has been revealed” (Shelf Awareness).

Raves and Reviews

“[A]s always, Ware builds the suspense to the breaking point and then drops a murder into it. . . . You can’t doze with Ware, so save this one for a rainy-day read.”
The Globe and Mail

“This is Ruth Ware like you’ve never read her before. A pulse-pounding opening launches you into a cat and mouse game of deadly intrigue that will push Jack Cross, Ware’s new, superb heroine, to her absolute limits. A rocket ride that will satisfy the biggest thriller addicts out there.”
DAVID BALDACCI, #1 New York Times bestselling author of Simply Lies and The 6:20 Man

“It’s exciting to watch Jack do what she does best: inveigle her way into places she doesn’t belong, escape at the last moment in panic mixed with exhilaration . . . [Readers] will be rewarded with a satisfying and surprising denouement.”
The Wall Street Journal

“From its resourceful, resilient protagonist to its seamlessly constructed, au courant plot, everything about Ware’s newest novel is guaranteed to keep her fans up way past their bedtimes.”
The Library Journal (Starred Review)

“Ware's latest thriller will not disappoint, different as it is from some of her earlier books . . . The action and tension are relentless from the opening to the conclusion, which will astonish, but certainly not dismay, readers, who will be captivated by this very original and very real protagonist. It has been said that in Ruth Ware’s books the pages just turn themselves. She has been heralded as ‘the new Agatha Christie’ for good reason.”
Booklist (Starred Review)

“[A]nother page-turning thriller.”
Associated Press News

“Ware is always a master of setting and atmosphere.”
Kirkus Reviews

“[A]nother page-turning thriller.”
Associated Press News

“[A] total seat-of-your-pants thriller . . . [C]omparisons to The Fugitive are inevitable, as the plot concerns our canny, resourceful heroine trying to evade capture and clear her name following the shocking murder of her spouse. Top-notch beach book.”
Philadelphia Inquirer

Zero Days will not disappoint with its jaw-dropping plot, well-rounded characters, and classic Ruth Ware-ian feminism.”
The Miramichi Reader
