Cosmic Kev - Andrew Donkin

When Kevin tells his class he's seen a UFO he's immediately branded a nut.

Wishing he'd never opened his mouth, Kev sets out to prove the existence of extraterrestrial life once and for all. However, before he gets a chance to find any aliens, aliens find him!
Being abducted by the Technobots seems to be the answer to all his problems. His reputation as a galactic problem-solver is known the length and breadth of the universe. However, when it becomes evident they don't intend to let him go, things get serious.
Luckily, a surprise rescue is on-hand, but escape isn't easy. And so the interstellar chase begins.

This is a second adventure for the intrepid hero of Colour Me Crazy.
