If you like Louis L'Amour, James Patterson, pulpy grocery-store serial bodice rippers, mystery, & thrillers, this is the place for you. Authors are identified by their gender (Women v. Men).
There's a handful of self help and health books (heavy on the diabetic cookbooks and prostate problem guides), some audiobooks and a few "craft" books (one ancient How To for pine cones, ahem). The shop has a good vibe and caters to the trade paperback crowd (hence the name); when it's hot outside and you want a frothy read, this is the place for you.
