Based on the selection, I'd say most folks come here either for the comics downstairs or the extremely large selection of Harlequin romance novels. If you're a fan of either of these genres, The Paperback Exchange could easily warrant a five star rating.
Seeing as how I don't have an interest in either, the selection for me was pretty limited. However, after some concerted digging, I plucked a copy of The Memory Keeper's Daughter from the shelf. It kept me entertained on my flight back to New York which is pretty priceless considering that it saved me from flipping through the SkyMall magazine again!
