Snakehead (Alex Rider Adventure) by Anthony Horowitz
This is a great book for people who love action stories. This is the most intense Alex Rider book yet, and as such it also contains the most violence (not graphic, but frequent). There are also some scenes (one in which Alex is covered in rats and another where he is going to be farmed for body organs) which readers may find disturbing. Alex is offered alcohol a few times, but he always declines. There is also one reference to topless women in a Thai bar.
Alex is recruited by the Australian government to help an undercover agent penetrate the Snakehead. The Snakehead is an Asian gang that is connected to Scorpia and known for smuggling, weapons, drugs, and even people. Alex is done being used by the government and is completely prepared to turn the assignment down, until he learns that the agent he will be working with is actually his godfather. Alex sees the mission as his only chance to learn more about his parents. But instead of helping Alex learn about his past, the mission only leaves Alex with an uncertain future. Can Alex escape from Scorpia for a second time, or will his luck finally run out?
