Does for spirituality what Sophie's World did for philosophy.
Theo is fourteen, Parisian, and slow to get up in the mornings. His parents love him, and want him to choose his own life, his own faith, so they have deliberately avoided giving him a religious education.
Theo is 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 show the varieties and depths of faith that exist in other places, other cultures.
