Tim's Temperamental Time Machine

Brilliant spires of a futuristic city, round houses of the past, wonders of advanced technologies contrasting with intense labour and squalour. These are some of the experiences of Tim, an eleven year old underachiever after he stumbles upon a seventies-style egg chair. Where did it come from, and when, and why? What does it do? And more to the point – does it work properly? Can the lessons of the past and future help Tim in the here-and-now? Will Jordan Armstrong ever stop picking on him? Will his team ever score a goal in P.E.? And what is it that they’ve found in a local Iron Age dig?
