Blue hardcover novel with lighthouse bookmark

Hey there, I lost my blue hardcover novel 'The Harbor Code' yesterday around 3pm near the Cotton Exchange on Front Street in Wilmington. It's a 6x9 blue cloth-bound edition, about 320 pages, with a red satin ribbon bookmark poking out. The corners are a bit worn from travel. Inside the back cover there's a tiny doodle of a lighthouse and a faded note in my grandmother's handwriting. This book means a lot to me—it was a gift from her, and I really need it back. If you found it, send a message and we can arrange a pickup. Thanks so much.
