Found this afternoon around 3:15pm outside the Library of Birmingham on Broad Street. It's a blue paperback edition of The Midnight Library by Matt Haig, a bit worn at the spine but still clean inside. A green bookmark with a tiny fox doodle sticks out about an inch, and there's a small 'Book Club January' sticker on the back cover. The cover has a little creasing along the bottom edge, and the margins show light coffee stains from a cafe visit. I'm glad to help, and if it's yours, ping me here and we can get it back to you.
