The delightful third book in the multimillion-copy internationally bestselling seriesFirst he tackled happiness. Then he took on love. And now Hector, our endearing young French psychiatrist, confronts the persistent march of time.

His patients lament that there is not enough time in the day. Or they feel that life is passing them by. And in one case, a young boy turns the problem on its head: he's impatient to grow up! Hector himself is increasingly aware of time: he doesn't feel quite so young anymore, and the clock is ticking on his relationship with his beloved Clara.

So as time flies, so does Hector in his latest adventure, traveling around the world and charming us with his inimitable blend of open-minded inquiry and subtle wit as he journeys to understand the past, the future, and how best to enjoy the present.
