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).

“Ruth Ware’s action-packed thriller Zero Days is as much an exploration of grief as it is a warning about the vagaries of technology.” –BookPage.

“Ruth Ware is one of the most versatile of crime writers… Jack is an invigorating character and her quest is both impressively plotted and moving.” –Literary Review.

“[Ruth’s] novels tend to fall into an Agatha Christie one or an Alfred Hitchcock one. And this new one, Zero Days – this is definitely an Alfred Hitchcock one… It’s just one of those novels where it starts fast, it keeps going fast and it goes fast all the way through to the end.” -Adrian McKinty, author of the award-winning Sean Duffy series.

“This had me on the edge of my seat… I got caught up in all the fictional suspense!” –First for Women.

“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, New York Times-bestselling author of The 6:20 Man and Simply Lies.

“A gruesome murder, a grieving widow and a race against the clock to uncover a dark conspiracy… Zero Days is a full-on, paranoid thrill ride with sky-high stakes and a thoroughly absorbing premise that’s never less than shockingly believable. This rare peek into the shadows of the dark web is visceral, human and terrifying. Five stars.” -Janice Hallett, bestselling author of The Appeal and The Twyford Code.

“She’s done it again. A breathless action thriller which packs and emotional punch, Zero Days is Ruth Ware’s best yet.” -Clare Mackintosh, multi-award-winning author of I Let You Go.

“This is Ware at her best, moving us carefully and efficiently into a book about … well, I don’t want to spoil it. Suffice it to say that, as always, Ware builds the suspense to the breaking point and then, drops a murder into it.” –The Globe and Mail.

“Zero Days retains all the agonizing suspense of [Ware’s] hits, but adds a rocket-fueled, high stakes plot, described—aptly, IMO—as Mr. & Mrs. Smith meets The Fugitive… Just when you think you know where this is going, Ware surprises you with a twist in this satisfying summer thriller.” –Amazon Book Review.

“Ware’s fast-paced fugitive story made me breathless.” –Minneapolis Star Tribune.

“The best thriller you’ll read this year. From its explosive opening to that dizzying first twist, Zero Days is a fast-paced – but also very touching – ride.” -William Shaw, author of the DS Alexandra Cupidi series.

Just don’t forget to breathe…” -Jack Jordan, Sunday Times-bestselling author of Night by Night and Do No Harm.

“You may recognize this story as a 21st century version of the movie, The Fugitive, with similar action and suspense. Zero Days… another exciting thriller by Ruth Ware!” –The Southern Bookseller Review.

“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.

“Zero Days by Ruth Ware is another super thriller! A showcase of the versatility and depth in Ruth’s craft. This one is a suspense rollercoaster.” -Steve Cavanagh, Sunday Times-bestselling author of the Eddie Flynn series.

“Ware switches things up with a high-stakes, high-tech novel of Hitchcockian suspense (think The 39 Steps) that deftly demonstrates why she is the chameleon of crime fiction. 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.” –Library Journal.

“[A] total seat-of-your-pants thriller…. comparisons 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.

“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.

“Church keeps the listener invested with fast pacing and a distressed tone adding to the tension as Jack becomes even more filled with anxiety. [She] enlivens each character. This is a thriller worth listening to.” –Audiofile.

“Zero Days was unlike any of Ruth Ware’s previous books. It read like a fast-paced spy novel or a female Jason Bourne . . . There was a great perspective on loss and finding the strength to go on when you don’t think you can. Ultimately it was an action packed thriller about a girl on the run. If you enjoyed The Fugitive or Mr. and Mrs. Smith, you will love Zero Days.” –Mystery & Suspense.

“[Ware] layers her story with fascinating details about [an] unusual profession while offering an implicit (and clearly well-researched) warning about the vagaries of technology. The book’s focus on the impact of intense grief is balanced by glimmers of hope among the devastation.” –BookPage.

“The author of The Woman in Cabin 10 and In a Dark, Dark Wood is back with another page-turning thriller… Ware has a knack for creating female protagonists worth rooting for and Jack, ‘five foot two’ and a fan of eyeliner, is no exception… Along the way, there are some fun twists and turns, and Ware fans, or fans of quickie thrillers in general, will probably finish it in a weekend.” –Associated Press.

“Zero Days is a lot of fun… a fast and exciting ride-along with the pluckiest fugitive since The Fugitive.” –St. Louis Post-Dispatch.

“[A] timely novel that never lets up for a moment… Zero Days is an infectious read with terrific plotting and a protagonist you cannot stop rooting for until the end.” –Bookreporter.

“In this novel, tech is front and center… There’s plenty of excitement—chases, break-ins, shady bitcoin deals, an impending medical emergency… and Ware is always a master of setting and atmosphere… Lots of adrenaline-driven action.” –Kirkus Reviews.
