Scorpia Rising (Alex Rider Series #9) by Anthony Horowitz

Scorpia Rising (Alex Rider Series #9)
Scorpia has dogged Alex Rider for most of his life. They killed his parents, they did their best to con Alex into turning traitor, and they just keep coming back with more power. Now the world's most dangerous terrorist organization is playing with fire in the world's most combustible land: the Middle East. No one knows Scorpia like Alex. And no one knows how best to get to Alex like Scorpia. Until now.

The chases have never been more intense, the fights more treacherous, or the risks so perilous to mankind. And this time, Alex won't get away.
