★Ware, Ruth. Zero Days. Gallery. Jun. 2023. 368p. ISBN 9781982155292. $29.99. THRILLER

When her latest job testing the physical and digital security of a company goes awry, Jacintha “Jack” Cross ends up in police custody. At this point, Jack would normally call her husband Gabe, who directs their operations online from home, and have him get their client to vouch for them. However, for some reason Gabe is not picking up Jack’s calls. Hours later, when Jack finally arrives home, she discovers why Gabe is not answering his phone: he has been murdered. As the police question Jack about what she found, she begins to realize that she is shaping up to be their number-one suspect. After putting her own spin on Christie’s And Then There Were None with One by One, and then paying homage to the Golden Age of mystery writing with The It Girl, 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. VERDICT 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.
