I've just finished reading the 7th book in the series, Snakehead, which was released just before Christmas. I must say this book is full of plot twists that keep you on your toes. It was so exciting I read it as soon as I came home from school! Horowitz uses such powerful description and never leaves a paragraph without detail. I honestly feel as if I'm witnessing what Alex is going through on every journey!
If you haven't read any of the books, Alex Rider is a 14 year old boy from London who one day was approached by a Special Operations service called MI6, only to find out that his Dad and his Uncle had worked for them, but they had both died aswell as his mother.
MI6 recruit Alex as an undercover child on 5 separate missions, with an extra from the American CIA and Australian Secret Intelligence Service in the lastest book titled Snakehead.
If you haven't read any of the series, the author is Anthony Horowitz and the first book of the series is called Stormbreaker. I recommend all of the books to you!
