This was a very good book. It had lots of adventure. It is about a boy named Alex Rider living with his uncle, Ian Rider. His uncle dies supposedly in a car accident. But Alex finds out that his uncle was murdered. He also finds out that his uncle was a spy for the MI6. Alex is hired to take his uncle&#65533;s place and complete his last mission. His training will only be two weeks. Will he complete the mission or will he be left behind in the graveyard with his uncle. This is a great book and you should read it.
