Ghost Protocol

Kevin and Jason Reyes were just two bored twins in Washington Heights, burning CDs and jailbreaking phones to help their mother make rent. Then their grandfather died - and left behind a debt that made no sense.

What starts as grief becomes an investigation. What starts as an investigation becomes a targeted strike against a corrupt bank manager laundering money for the Russian mafia, an Israeli crime syndicate, and the Albanian mob - three networks that have spent years quietly bleeding isolated elderly people dry, one "friendly" phone call at a time.

Armed with nothing but self-taught code, a Flipper Zero, and a family debt they refuse to let stand, the twins pull off a takedown that would make Elliot Alderson proud. But taking down a system doesn't mean the people running it disappear - and when a syndicate hacker traces the wreckage back to their own front door, Kevin and Jason learn the hard way that some ghosts need real training to survive.

Fast, funny, and unflinching, Ghost Protocol is Hackers with a conscience, The Boondocks' sharp tongue, and Mr. Robot's paranoia - a story about brotherhood, grief, and what it costs to fight a machine built to eat people like the ones you love.
