I belong to a wonderful online reading group called Goodreads. I've been a member since November of 2008. You can keep track of the books you have read, are reading now, and what you plan to read in the future. I love reading reviews that my friends have written and find out about authors and books I hadn't heard of before. There are also smaller groups within the group that anyone can join.
I have met some wonderful friends from all over the country and in foreign countries as well through Goodreads. I look forward to chatting with good friends every day. This group has really enriched my life and I strongly encourage everyone to join!
