Element of Fun 
We asked each “girlfriend” to bring a favorite book to exchange. It could be a book they already own or something interesting and new they just picked up.
This is a great way to learn about each other’s interests and to introduce your friends to a book you really enjoy. Consider sharing one of your favorite summer novels or non-fiction works like cookbooks and travel books. There a plenty of online bookstores that will help you make your selection.
Make it even more fun and ask each guest to wrap their selection. Each guest picks out a book and then as the opportunity to exchange with other guests if desired. You’ll have fun seeing how well you each can judge a book by its wrapping
