What this book is about

Jack Cross and her husband Gabe make their living as a penetration testing team — hired to break into companies to find their security flaws. Then Gabe is found murdered, and Jack is the prime suspect. She knows she didn't do it. She also knows she has to stay ahead of the police long enough to find out who did — using every skill she has. Ruth Ware's tightest, most propulsive thriller: a cybersecurity procedural and a wife's race to save what's left of her life.
