1. Does what you read vary by the season? For instance, Do you read different kinds of books in the summer than the winter?
2. If so, do you break it down by genre, length of book, holiday, or...?
I think what I read does vary by the season, but not because I think about it when I make up my lists. I tend to read lighter fare in the summer--not exactly beach reading, since I don't live by a beach, but perhaps not as serious. The McKid is home with me more in the summer, so my distraction level is on high, and by the end of the day I am more tired and more frazzled that during the school year when she is at preschool.
I also don't want to read "darker" things in the summer. Down here it's oppressively hot much of the summer. I don't want to add sorrow and pain to the heat! So, I'd read Heyer, or Dickens, or Austen or Trollope in the summer. I'd read Greene, Waugh, Mistry and their like in the winter. Shakespearian comedy in the summer. Shakespearian tragedy in the winter.
For the past year I've set myself seasonal challenges, and have made up a reading list to read from. I try to mix up types of books on those lists. But overall, I think the summer one will be lighter than the winter one was.
