I have read Hape Kerkling's book several times, and it is a mainstay in my "Camino Library". I find it to be the story of a man who reached a point in his life when he realized that some changes had to be made, somewhere and somehow, so he came upon the Caminio. My only regret about this book is that I cannot read it in the original German, because no matter how good the translation, something is always lost, case in point the title: "I'm Off Then" might have been translated in North American English as "I'm Out of Here" both similar in meaning, but what is missing in the English translation is the contextual meaning of "I've had Enough" (this courtesy of my daughter in law, a native German Speaker) So it makes me wonder how many other subtle meanings I am missing.
That said, I love the book: His story, the changes he observes in himself, his daily observations, the friends he makes along the way, his challenges and, of course, his humour.
