Blue passport in black sleeve, lost yesterday

I lost my blue passport yesterday around 3pm near the Starbucks at Columbia Center Mall in Kennewick. It's in a black fabric sleeve, with a small cherry-blossom sticker on the back and a tiny coffee stain on the inside cover. The passport itself is the standard blue cover, and I really need it back because it's my only travel document for now. If anyone found it, please message me; I can meet in the Tri-Cities area to pick it up, since we were planning a big trip soon and I can't replace it quickly.
