Out of This World by Ali Sparkes
Tyrone Lewis is messing about in the woods, trying to keep out of trouble, when he stumbles upon something weird . . . a glowing lump of rock or metal or something. Whatever it is, it gives him an amazing power. Which is cool at first, until Ty's new powers start attracting attention, and soon he's being followed by two sinister agents who seem intent on 'collecting' him. But Ty has no intention of letting that happen. So now he's got to RUN . . .
