Grading Note: Normally, the pages of the older paperbacks have yellowed to various extents over time, but I will note any yellowing if out of the ordinary. I will do my best to note any defects in the book---exterior and interior---but if I should miss any notable defect, please let me know, and you shall always have the option to return the book for a complete refund.
