I started an online book club and my pick was The Tomb (I'll get people hooked if it's the last thing I do!

). I've never been part of a book club before and we are still starting out. I was wondering if you all would help me with some possible discussion questions to bring to the table? The ones I have so far are:
What was your first impression of Jack, Gia, and Mr. Bahkti?
What do you think of Jack's fight violence with violence approach?
We have the book broken down in sections and are still on the first section, but any suggestions for any of the book would be greatly appreciated. This is the first book club I've been a part of. Thanks in advance!
