Hamish and the gravityburp

This book knows something terrifying: that the people of Earth face their gravest, grimmest threat yet! When Hamish arrives home to find his mum and his brother lying flat on their backs ON THE CEILING, he knows there's something seriously wrong (again) in the town of Starkley. What is the strange burping noise he keeps hearing? Why are weird seeds suddenly falling from the sky? And should he be worried about the odd woman with a cone around her neck? All Hamish and his gang the PDF can be sure of is that an adventure is coming. And that means two things:* You have to be prepared* You have to prepare a sandwich.
