Kat Frank knows all about loss. A widowed single mother, Kat is a cop who trusts her intuition, honed through years of on-the-beat police work. Picked to lead a pilot program that has her paired with Lock, an AIDE (Artificially Intelligent Detective Entity)—a hologram that is activated by a device on Kat’s wrist—Kat’s gut reactions about people and motives come up against Lock’s statistical calculations and data analysis that can be devised in seconds.

But as the two missing person’s cold cases they are reviewing suddenly become active, Lock is the only one who can help when the case begins to target Kat personally. AI versus human experience. Logic versus instinct. With lives on the line, can the pair work together to solve the mystery in time?

A dazzling debut from an exciting new voice, In the Blink of an Eye asks us what we think it means to be human.
