Spy School, tech giants

Hello, my name is dean and this is my first story.
Important: This continues from the end of 'Spy School Goes South'
Ben is thinks he is finally settled at spy school as he hasn't been active for a few weeks. That is, until he gets called on a new mission. He must face cyber terror, big bosses and crazy phones...

Feedback is appreciated.
The characters are owned by Stuart Gibbs, a great author you will probably know.
