The Danger Gang by Tom Fletcher

Franky can’t wait to move to his new town – although he wishes he didn’t have to leave his best friend Dani behind. But everything changes after the storm, when strange green lightning and powerful thunder crash down on the town. From that night on, the kids who live on Franky’s street start to change. One by one, they become a little odd. A little unusual. Franky’s always wanted to be part of an amazing gang – just like his hero, super-spy Zack Danger! And soon, he realises that there’s real danger in store for himself and his new friends. And so the Danger Gang is born.
