Refresh your bookshelves without spending a dime, unless you want wine
Bring a book and plan to leave it behind in place of another interesting title.
Bring a wrapped book (or as many as you’d like) to trade and swap it for someone else’s. After gathering everyone’s submissions, each participant will take turns pulling new books blindly. After each participant has pulled a new book, a barter and trade period will take place for any needed switches.
