Silent Code (2026)

Silent Code—Book 3—FIRE Series

A single line of code can bring a nation to its knees… and someone has just pulled the trigger.

When a coordinated cyberattack shuts down power grids, hospitals, and financial markets across the country, FIRE is thrown into its most dangerous mission yet. Isobel “Izzy” O’Keefe and A.J. “Coop” Cooper race to trace the breach, only to discover a horrifying truth—the blackout was merely a test. A far deadlier attack is coming, one capable of collapsing global infrastructure without a single bomb or bullet.

All signs point to a ghost in the digital shadows—Cipher, an elite hacker long believed to be a myth. As Faith and Dane dig into the dark web, clues lead the team from Boston’s failing systems to a hidden tech underworld in New York, where Coop and Izzy go undercover to lure Cipher out. But Cipher is always one step ahead—watching them through hacked cameras, erasing evidence, and issuing one chilling warning:

I told you to stop looking.

When the final attack countdown begins, FIRE races to stop Cipher before the world is plunged into irreversible chaos. But as the mission reaches its breaking point, Izzy’s worsening symptoms threaten to take her down in the field—and Coop refuses to leave her behind.

The world may have survived the attack. But for Izzy and Coop, everything is about to change.
