Translation of meteorological in German

We sat on the balcony and saw that the hotel had even a pool on the roof top but I did not have the courage to jump in. It just looked to dirty and as no one was in there I did not need to be the first.
For me it's a really I nice way to learn English vocabulary, verbs and grammar. I created a new vocabulary lesson about leisure and health. There are many words in that lesson.
I guess it is a very interesting book, but I did not entirely understand it. What did the author try to say, what message did he want to deliver? Do you want that I recommend another book?
