Flaco isn't the kind of kid who gets in trouble. He doesn't want to give his mom or his aunt Ana Flor any grief--they've had enough since his cousin Carlos died serving in Iraq. But he finds a whole lot more trouble than he bargained for when he and his friends Tiny, Maga??a, and Susi ride the bus from their Houston neighborhood to Diamond Park to buy a used car. And not just any car--a 1959 Impala convertible, a dream car. The transaction gets complicated fast, and Susi ends up with a knife in her hands, covered in blood. When Tiny has to disappear to avoid ICE, Flaco and Maga??a head south in the Impala to set things right. In a wildly impetuous move, the two boys cross into Mexico hunting for a trafficker named Anaconda, the man they believe is the real killer, to clear Susi's name. In a breathtaking, seat-of-your-pants adventure they manage to kidnap him but in the process they discover how little they ever actually understood about what really happened in Diamond Park.
