Science Fiction Book Club is an online book club on Facebook.
Each month the members vote on which science fiction novel to read and discuss and a weekly discussion question is posted every Friday.
There is also a weekly short fiction discussion.
Members also post about other science fiction novels and science fiction topics.
Group members live all around the world. Here is a Member Map.
Many Science Fiction authors as well as biographers/archivists have participated in Q and A sessions with the group.
