'Will?' asked Davina. 'What's going on?'
Will knew it was going to sound crazy. 'Okay,' he said at last. 'I'm going to tell you something that might sound a little strange. But believe me, it's true.'
A year has passed since Will Buster came back from the Gelmet Academy, where he uncovered Professor Gelmet's secret experiment in mind control. Each day he takes his old, battered HoverPod to school, loses interest in the lessons in the Learning Hall and plays games of Pointy Wibblers with his friend Myron Dort. Life's back to normal. Almost boringly normal. . .
Except for the tricks Will's eyes have started playing with him. Sudden flashes, shimmering lines. Then Myron vanishes, and Will finds himself drawn deeper and deeper into the mystery of his disappearance. Or is it a trap? Perhaps Professor Gelmet's experiment isn't over after all. But is it the Professor, or somebody else, who wants to catch him in their web?
