CORE Decipher
CORE Series | Book Two
One hacker. One impossible mission. Zero margin for error.
Coming Oct 21
Seth Alvarez has the ultimate power in a surveillance state: cyber invisibility. Using stolen tech that makes him a ghost to the all-seeing CORE system, he's the resistance's most valuable protector. But when CORE prepares a deadly upgrade that will crush all hope of freedom, Seth must make an impossible choice: stay hidden and keep saving lives one at a time, or risk everything by going undercover inside CORE's fortress for a chance to liberate thousands. Allying with a former enemy, Seth must pull off the most dangerous hack in history—one that will either liberate an entire nation or destroy everyone he loves.
In the Socialist American People, the Centralized Objective Record Exchange is a supercomputer and the government’s greatest weapon. CORE watches every move, flags every dissent, and houses enough data to maintain total control of the populace. Seventeen-year-old Seth Alvarez has learned to fight back one stolen edit at a time, using a rare tool to resist the regime from the frozen ruins of the ZONE. For months, he’s hacked profiles on CORE to keep refugees alive and his family safe.
But after a supply run turns into an ambush that leaves his father trapped and two refugees dead in the street, Seth realizes that patching problems one profile at a time will never be enough.
When he uncovers a secret program buried in the files of the legendary Takeo Yamada, he knows one move that could change everything. But it requires going undercover inside CORE itself—a mission more dangerous than he realizes. And time is running out. CORE is about to undergo an extensive upgrade, threatening Seth’s secret technology and his ability to deploy Yamada’s special program.
