Blue paperback novel with green ribbon bookmark

I lost my blue paperback novel 'The Edge of Dawn' yesterday around 3pm near the La Salle County Library on Main Street, just outside the cafe entrance. It's a softcover with a creased spine, a green ribbon bookmark, and a small coffee ring on the back cover. There's a handwritten note inside the front cover that reads 'hold fast' in black ink. It used to be a gift from my mother; it's become sentimental and I really need it back. If you found it, please ping me here in the app—I'd be forever grateful.
