Every year I choose a theme and every fourth or so book I read has to fit that theme. These are some ideas for themes for the years to come.

• Pulitzer Prize-winning novels
• ✔ Unread books on my shelf
• Books that inspired movies I've liked
• Re-reading a bunch of books I've liked in the past
• ✔ Books recommended to me by friends
• Books by European/African/Asian/South American (etc) authors
