Blue paperback poetry book with red bookmark

I lost my blue paperback poetry book yesterday around 3pm. It's a small 6x9 inch paperback with a soft matte cover, faded blue color, and a red ribbon bookmark sticking out between pages. There's a coffee stain on the back and a pencil note in the margin on page 42. Inside the front cover I stuck a tiny round sticker with my initials 'AO' in black marker. I last saw it near the entrance to the Cape Girardeau Riverfront Park along Main Street, by the benches near the river. It has sentimental value to me; it's the only copy of this collection I could find, and I'm really hoping to get it back.
