Does for spirituality what Sophie's World did for philosophy. Theo is fourteen, very clever, reads a lot, loves computer games and the Greek myths.

But then, suddenly, he falls ill. His rich aunt Martha decides that they must roam the world to find a cure for his malaise. What follows is a tour of the world's religions and religious sites, with the sceptical, quizzical Theo being shown the varieties and depths of faith that exist in other places, other cultures. All this is handled with real style, pace, wit and clarity.

The book is a thoroughly enjoyable introduction to why and how people believe in their God - even Dave Allen would have liked it.
