Now a major motion picture starring Simon Pegg, Rosamund Pike, Toni Collette, and Christopher Plummer The international bestseller with more than two million copies sold “Once upon a time there was a young psychiatrist called Hector who was not very satisfied with himself. . . . And so he decided to take a trip around the world, and everywhere he went he would try to understand what made people happy or unhappy.” Hector travels from Paris to China to Africa to the United States, and along the way he keeps a list of observations about the people he meets. Combining the winsome appeal of The Little Prince with the inspiring philosophy of The Alchemist, Hector’s journey around the world and into the human soul is entertaining, empowering, and smile-inducing—as winning in its optimism as it is wise in its simplicity.
