Throttle's Run

Blood runs faster than the law on Chicago's South Side.

Sienna Harper spent seven years racing toward danger as a South Side paramedic, treating gunshot wounds and gang violence while everyone else ran away. When she responds to an execution in progress and saves a dying Urban Sentinels prospect, she doesn't just cross paths with Chicago's most dangerous MC—she crashes headlong into their Road Captain.

And he's been waiting for someone reckless enough to match his speed.

Throttle survived his father's murder, ten years of adrenaline addiction, and countless firefights by never slowing down long enough to feel anything real. Speed is survival. Commitment is death. Until a paramedic with a backbone runs into his alley without hesitation, treats his brothers under fire, and makes permanent feel like acceleration instead of braking.

When the Alejandro Cartel declares war on Sentinel territory with military precision and massacre tactics, Sienna's casualty intelligence becomes the brotherhood's tactical weapon. She maps cartel operations through wounded soldiers, identifies command structures through dying enforcers, and proves herself essential to survival.

But Roberto Alejandro doesn't just want territory—he wants leverage. And Throttle's woman just became the highest-value target in Chicago.

Welcome to Chicago's South Side, where one paramedic's intelligence just became the Road Captain's reason to survive every run.

Urban Sentinels MC: Former soldiers and street fighters who watched their neighborhoods rot while the system failed them. Now they ARE the law. Protecting their streets. Enforcing consequences. Riding together. One call, all answer.

The system failed. The Sentinels deliver.
