Blue paperback travel guide to Central Louisiana

I lost my blue paperback travel guide to Central Louisiana yesterday around 3pm near the Alexandria Mall on MacArthur Drive. It's a small 6-inch book with a creased white spine and a fleur-de-lis sticker on the back label. Inside, there's a handwritten note in green ink at page 12 and a dog-eared corner on page 72. This book has sentimental value—it's the only guide I have for planning a weekend trip through the bayous, and I really need it back.
