An electrifying novel from the Carnegie medal-winning Kevin Brooks. Now a Netflix movie starring Maisie Williams (Game of Thrones).

Before the attack, sixteen-year-old Tom Harvey was just an ordinary boy.

But now fragments of a shattered iPhone are embedded in his brain and it's having an extraordinary effect . . .

Because now Tom has powers. The ability to know and see more than he could ever imagine. And with incredible power comes knowledge - and a choice. Seek revenge on the violent gangs that rule his estate and assaulted his friend Lucy, or keep quiet?

Tom has control when everything else is out of control. But it's a dangerous price to pay. And the consequences are terrifying . . .
