Sophie’s World introduces us to fourteen-year-old Sophie: a Norwegian highschooler who receives mysterious letters addressed to another girl, asking big questions. But who is the other girl? And who, for that matter, is Sophie herself?

To solve the riddle, Sophie embarks on on a fantastic philosophical saga, and as the book hurtles through several millennia of philosophy – raising profound questions about the meaning of life and the origin of the universe – the dimensions of Sophie’s world grow ever wider.

An addictive blend of mystery, fantasy and philosophy, Sophie’s World is an international phenomenon which has been translated into sixty languages and sold more than forty million copies worldwide.
