Paperback novel with yellow note found near Broad Street Market

I found a paperback novel this morning around 9am on the steps outside the Broad Street Market on Market Street, Harrisburg. The cover is bright red and a bit worn, about the size of a standard mass-market book, with a purple bookmark peeking out from page 180. Inside the back cover is a yellow sticky note that says 'For Sam' in blue ink. There are a couple of coffee stains along the edge and a small crease on the bottom corner, but it looks well-loved. If the owner recognizes these details, please reach out and I’ll help get it back to you.
