Luis Fuentes has always been sheltered from the gang violence that nearly destroyed his brothers' lives. But that hasn't stopped him from other thrill-seeking behavior like scaling a mountain in the Rockies or dreaming of a future as an astronaut. Nikki Cruz lives her life by three rules boys lie to get their way, don't trust a boy who says "I love you," and never date a boy from the south side of Fairfield. Then she meets Luis at his brother Alex's wedding, and suddenly she's tempted to break all her rules.
Getting Nikki to take a chance on a south sider is Luis's biggest challenge, until he finds himself targeted by Chuy Soto, the new head of the Latino Blood. When Chuy reveals a disturbing secret about Luis's family, the youngest Fuentes finds himself questioning everything he's ever believed to be true. Will his feelings for Nikki be enough to stop Luis from entering a dark and violent world?"
