I wouldn't buy a book on the strength of either thing. That's when you pull out your Kindle and read something you want to read... or pull out your emergency book, which all serious readers carry about with them. </quote

Yes, I am talking about the situation when you have just finished your emergency book, or (horror of horrors) when you left it at home because you were stupid and took the wrong bag and forgot to repack.

I am with you on emergency books. But I am also not always quite there in my brain when stressed.
