Blue Penguin Classics hardcover with yellow bookmark

I lost my blue Penguin Classics hardcover of The Long Winter yesterday around 3pm, probably outside the North Platte Public Library on 4th Street. It's teal-blue with a slightly bent spine, and a bright yellow ribbon bookmark peeks out from between the pages. There's a small purple sticker with the initials JL on the inside cover and a faint coffee stain along the back. It's sentimental—it's my grandmother's gift, and I really need it back.
