As I mentioned before, I firmly believe daughters should get to choose those to invite. When it came to forming Skylar's club, it was hard to follow my own advice. While the majority of the Bookworms came from Skylar's school, she chose several girls whom I did not know. She also left out several girls whom I thought would be perfect and whose moms I particularly liked and wanted to get to know better. But I listened and, again, my daughter proved to have excellent instincts.
Bookworms is a wonderfully diverse group of independent freethinking girls and moms.
For your first meeting, pick out a book together and send invitations asking everyone to read the book in advance. I suggest choosing a book that has been a favorite at your house. Try to give potential club members at least 30 days notice so they have ample time to read the book. Next, help your daughter select or make up discussion questions about the book. Girls have wonderful ideas and opinions and are willing to share when asked.
