Face Last Seen (December 15, 2026)

When a dangerous AI weapon disappears, all hell breaks loose in a high-stakes thriller by Jeffery Deaver and Isabella Maldonado.

A high-stakes theft draws federal agent Carmen Sanchez and brilliant hacker Jake Heron into the hunt to recover the stolen Epsilon Core, a revolutionary autonomous weapon engineered to operate beyond human control.

An enemy in the shadows is assembling the final components to unleash it, causing unimaginable casualties. To stop the unthinkable, Carmen and Jake—experts in exposing intrusion and threats—must track down a mastermind who hides in plain sight behind a perfectly chilling disguise.

Racing against mercenaries, arms dealers, cult conspiracies and a nemesis from Jake’s past, the unlikely partners must navigate a complex and increasingly personal relationship—one put to the test when Jake himself falls under suspicion.

As the clock runs out, and the Epsilon Core’s devastation looms, Carmen must decide if she can trust her partner, a man she may not even recognize anymore.

The third installment in the Sanchez & Heron series is coming out on December 15, 2026.
