That's a question somebody recently asked me. Whenever I go to university (a 80 minutes train ride) I pack my little book bag and sometimes I have up to four books with me (always at least two).
Let's take for example yesterday. I had with me "Indulgence in Death" by J.D. Robb, "Scoundrel" by Zoe Archer, a short book by Betty Neels and my new Sony Pocket (will post about my ereader in the next days, it's a nice toy but will never replace print books) with six books on it. The reason why I had so many books with me is that I didn't know before leaving home in which reading mood I would be on the train. Would I want something with death, action or sweet love? In the end I finished the new J.D. Robb and also read the book by Betty Neels (on my way back home).
I don't really need to carry around four books but I want to be able to choose from different types of romances so I don't mind the extra weight. Today I will take three books with me - just in case :)
Are you also carrying around more books than one just to be prepared?
