I bought it at the base to put on my night table, to fall asleep more easily after an evening on the computer. It did not have the desired effect ... The book is quite addictive, and strength to say, "Come on, a chapter" is finished to regret the next day. This is the first book I have read that without me the choice is dictated by my French teacher, and my choice was necessarily focused on this book including the famous response to "big question about life, the Universe and Everything "and mythologized. I now look forward to continue playing next volumes.
