Some thoughts before joining a book group:
1) Read the book all the way through before the meeting. Sometimes this is hard to accomplish. Just do the best you can.
2) Be open-minded.
3) Share, and really listen when others give their opinions.
4) Have a good time–VERY important! 🙂
5) Mixing fiction and nonfiction titles is never a bad thing.
Many novels have lots of characters, and it can be difficult to keep them straight. In one of my groups, whoever leads will often list characters on handouts as a discussion guide. Basically, put characters into groups.
