As one local business closes its doors another one will soon be opening them up. Book Nation, which just celebrated their 20th anniversary as a business, will be closing its doors for the last time this weekend. The bookstore, currently on Wabash Avenue, is selling out the last of its inventory at discounted prices until they close Saturday. The area will not be empty long as the space has already been leased to a new boutique which is set to upon within a month.
