Navy blue passport with gold seal

Yesterday around 5:15pm I realized my passport was missing after leaving the Starbucks on Fort Campbell Boulevard in Clarksville. It's a standard US passport in a navy blue cover with a gold eagle seal; the cover has light edge wear and a coffee ring on the back. I had a small sticker with the initials 'AF' tucked on the inside page as a tiny bookmark. This passport is essential for an upcoming trip next week, and it has sentimental value because of the memories attached to it—I'm really hoping it turns up. Any help would mean a lot; I just want to get it back and move on with my plans.
