Fraincois Lelord, Le voyage d'Hector ou la recherche du bonheur

French is not my strength, so I had to read it in German. What a lovely book!

The psychiatrist Hector is traveling the world to find out what happiness is. It truly made my day on the flight back from Germany. If you're looking for a nice read that leaves you with a big smile in your face, try this book!

Hectors Reise - oder die Suche nach dem Glueck (German version)
Not sure if there is an English translation yet, I found a Spanish version on Amazon.
