Blue US passport with crease on cover

Yesterday around 3pm I realized my blue US passport was missing after I left a bag in the parking lot behind Target on Mount Rushmore Road in Rapid City. The cover is dark blue, with a noticeable crease along the bottom edge, and there's a faint coffee ring on the back. This passport is essential for an upcoming trip and holds sentimental value — I'm supposed to travel next week, and I really need it back. If someone found it, please drop it off at the Rapid City Public Library lobby on 2nd Street, or message me here; I’ll be incredibly grateful and can arrange a quick pickup.
