To be thirteen is worthless, Trino Olivares thinks. Trino has three little brothers he's supposed to look after, but no father he can look up to. He rules at video games, but in the classroom, and out in the real world, he's barely getting by—just like his mom, who scarcely manages to pay the bills and feed her kids by working all the time.

Trino gets angry when he looks around at his terrible life. But when Rosca, an older teen with a vicious streak, invites him to start hanging with his crowd—and maybe make some quick money, too—Trino doesn't know what to think. What kind of choices does he have, anyway? To run or die?
