ROGUE AGENT!

Sir Damian Cray: Millions adore him. He is a philanthropist, peace activist, and the world's most famous vintage pop star. But still it's not enough - not if he is to save the world. Trouble is, only Alex Rider recognizes that it's the world that needs saving from Sir Damian Cray. Underneath the luster of glamour and fame lies a twisted mind, ready to sacrifice the world for his beliefs.

Alex has seen his share of evil masterminds in the short time he's been an agent of MI6. But in the past, Alex has always had the backing of the government. This time, he's on his own. Can one teenager convince the world that the most popular man on earth is a madman bent on destruction - before time runs out?
