Blue Penguin Classics paperback lost near Lewiston Public Library

Yesterday around 3pm I was at the Lewiston Public Library on Main Street when I must have set my bag down and left my blue Penguin Classics edition of Pride and Prejudice on a bench. It's a standard mass-market paperback, about 8 by 5 inches, with a blue cover and a white penguin logo, roughly 320 pages. It has a red ribbon bookmark sticking out between pages 120 and 121, a coffee stain on the back cover, and dog-eared corners. This book means a lot to me—it's a gift from my aunt and I’ve read it several times; I really need it back. If anyone found it, please drop it off at the library or message me here; I’d be forever grateful.
