Lost & found printed media in Lancaster

Blue paperback mystery novel, Lancaster, lost

I lost my blue paperback copy of 'The Nightingale Street' yesterday around 3pm near the Lancaster Central Market on Market Street. It's a standard paperback, about 350 pages, with a blue cover and a small gold crown emblem in the top corner. There's a coffee ring on the bottom edge and a green ribbon bookmark peeking out from page 118. On the inside of the back cover there's a faded sticker from the Lancaster Book Club. It was a gift from my aunt and I was really into it—has sentimental value, and I’d be beyond grateful to get it back.
