This is the paperback edition of Project Hail Mary. I bought it new at a bookstore and have only read it once. I read it with a cover on, and will ship it including the cover. The condition is listed as "soiled," but there is a stain-like discoloration on the bottom edge of the second volume (see photo 4). This was present from the time of purchase.
