When Alex Rider crash-lands off the coast of Australia, the Australian Secret Service recruits him to infiltrate one of the ruthless gangs operating across Southeast Asia. Known as snakeheads, the gangs smuggle drugs, weapons, and worst of all, people. Alex accepts the assignment, in part for the chance to work with his godfather and learn more about his parents. What he uncovers, however, is a secret that will make this his darkest and most dangerous mission yet . . . and the knowledge that his old nemesis, Scorpia, is anything but out of his life.
