Stormbreaker: Alex Rider Book #1, Anthony Horowitz

Nothing prepares 14-year-old Alex Rider for the news that the uncle he thought he knew was really a spy for MI6 – Britain's top-secret intelligence agency. Forcibly recruited into MI6 himself, and armed with top-secret, state-of-the-art gadgets, Alex is sent to finish his uncle’s final mission – a mission that involves a wealthy sinister businessman and his new tech creation: a super computer called Stormbreaker.

The stakes are high and things are about to get deadly. . .
