Hardcover travel guide, blue spine

I lost my hardcover travel guide, Pocket Atlas of California, yesterday around 3pm. The cover is cream with a blue spine and there’s a coffee stain along the top edge. Inside, there’s a blue elastic bookmark, a tiny compass sticker on the back cover, and a faded note that says 'someday road trip' in my friend's handwriting. It was a gift from my grandmother and has sentimental value, so I really need it back. I last had it outside the Sacramento Central Library on I Street, near the entrance by the bus stop. If anyone finds it, please let me know—this little book means a lot to me.
