Matrix's War. Leatherneck Brotherhood MC, #13

She's testifying against a prison gang. Now a Marine prospect will eliminate anyone hunting what's his. Jordan Hayes spent five years as a corrections officer before trading violent inmates for teaching self-defense-showing women how to protect themselves while waiting to testify against the Latin Disciples. But when she witnessed three gang soldiers beat a man half to death, she didn't know she'd just signed her death warrant.
Now a prison shot-caller has issued a kill order, coordinated hit teams are hunting her through Jacksonville, and the gang that's silenced seven witnesses thinks their twelve-year track record makes them untouchable. Matrix served six years as a Marine radio operator through two deployments before finding civilian life empty without brotherhood, without purpose. But when he spots surveillance patterns around a woman who doesn't know she's being hunted, every protective instinct roars to life.
She's his to claim. Anyone who threatens her dies. Jordan fights beside his brotherhood when gang soldiers assault their compound. Proves she's warrior enough to drop hostiles at seventy yards while chaos erupts around her. Makes him want something beyond prospecting for the first time since coming home. But Demon escalates with coordinated assaults, professional operators, and prison connections that make him believe his cell keeps him untouchable.
He's about to learn what happens when you threaten a Marine's woman. Matrix will eliminate every threat with methodical observation and deadly precision. Jordan's not just under his protection-she's his to claim, his to keep, his to defend until the only thing left standing is their future together. Semper Fi means forever. So does his claiming.
