I read cozy and historical mysteries, a bit of Paranormal/UF, and to mix it up, I read science and gardening books on occasion.
Book scouting sounds like one of those oddly intriguing careers, like a treasure hunter or a salvage diver. Mostly miss and every so often a massive hit but always the thrill of the chase.
Rare Books Uncovered is a collection of 52 stories from some of the more well known (relatively) scouts, librarians, and dealers in the business, each sharing their biggest, or most memorable 'score'. Rare first editions, ephemera and in one case, a flag.
This kind of stuff is my personal catnip and I ate it up. The cherry on top being a recommended reading section at the back, which will do nothing for the ever-growing size of my TBR.
