Blue Keys travel guide, dog-eared pages

I lost my blue paperback travel guide to the Florida Keys yesterday around 3pm near Mallory Square in Key West. It's a Keys Pocket Guide by Island Press, about the size of a small paperback, with a teal ribbon bookmark and a coffee stain on page 72. The cover is a bit creased from rain and salt spray, and one page is folded at the corner where I highlighted the lighthouse route. It has sentimental value because my sister gave it to me before this trip, and I really need it back to plan the rest of my days here. If anyone found it, please get in touch.
