Blue paperback travel guide with Alaska notes

I lost my blue paperback travel guide to Alaska yesterday around 3pm near the Soldotna Public Library on Main Street. It's a softcover, about 6 by 9 inches, with a bright red ribbon bookmark sticking out and a small coffee stain on the back cover. Inside the back pocket is a folded map of the Kenai Peninsula, and there's a handwritten note on the first page about our upcoming trip. This book is my go-to for planning the weekend drive, and it has sentimental value; it was a gift from my sister. I really need it back; please reach out if you've seen it.
