Slight tilt; line down spine; line next to spine; light overall wear. Top and bottom page-blocks have marker-line that hide stamps underneath. Inside back cover has a list of stamped dates - by this I infer that this book was part of some library, but without most library traces like tape, writing, or stamps on credits page, etc. (And no way was it read as many times as checked out - I'd guess 2 or 3 times by the light wear.) I don't find many used copies of books by Nolan, and his "Logan" series tend to be high-priced online.
