(sorry if this sounds like advertising, but cant resist!)
Whilst we are on the grand subject of weather, especially our current "heat wave", it reminded me of a very good (and short!) book i read recently - "The Alchemist" by Paulo Coelho. Its set mostly in the Sahara although starts in Spain - hence the connection with heat! The book is an absolute gem, a diamond in the rough! Definitely best read whilst listening to some vocal-less music: it really helped my escape from the huge mess that is my life! And the book told me many an important lesson (dont worry its not preachful - even though the main character is a spanish boy sheperd).
If you get the chance, read it this summer, its only about 170 medium sized pages long, and easily readable during a long journey.
I have a feeling im going to eget in trouble with this post...
