Found a paperback copy of The Great Gatsby this afternoon around 2:45pm behind the Susanville Public Library on Main Street. It's a blue paperback edition with gold lettering, a small coffee stain on the edge of page 23, and the spine is creased from use. Inside, there's a dog-eared bookmark shaped like a paw print sticking out, and the back cover has a faded sticker that says 'Library discard'—it's clear it's been read a few times but still in decent shape. If this belongs to you, drop me a line and we can arrange a meetup near the library bench.
