Black leather address book with contacts

I lost my small black leather address book yesterday around 3pm. It's about 4x3 inches, pebble-grain with a tiny gold clasp, and blue inked names on the inside pages. I was near Margaritaville Lake Resort at the Lake of the Ozarks when it slipped from my jacket pocket. The back cover has two tiny heart doodles and a coffee stain on page 7, plus a blue ribbon bookmark. It holds emergency numbers and a few personal contacts; it's sentimental and I really need it back.
