Zero Days, the pulse-pounding new mystery thriller by acclaimed crime author Ruth Ware, has debuted at #4 on the New York Times bestsellers list for hardcover fiction. You can find the full bestsellers list here.

An adrenaline-fuelled thriller that combines Mr. and Mrs. Smith with The Fugitive, Zero Days follows one woman’s 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).
