Horowitz, Anthony. Scorpia

Horowitz, Anthony. Scorpia [Alex Rider #5]. Philomel, 2005 [0-399-24151-5]
At the end of the last book, Alex was told his father was affiliated with Scorpia, not MI6. In this book Alex goes in search of Scorpia, an international crime organization. He finds out that his father worked for them and because of how MI6 tricked him before (in previous books), Alex decides to switch sides and become part of Scorpia. He gets entangled in a plot of Scorpia's to pit the USA and Great Britain against each other. Of course, at the end of this 312 page book, Alex once again saves the day and is convinced to go back to MI6. Once again Horowitz had written a great thriller/spy novel with a 14 year-old-boy as the main character.
