Found hardcover travel guide near Mall Del Norte

I found a hardcover travel guide this afternoon around 3:30pm near the Mall Del Norte entrance on Del Mar Boulevard in Laredo. It's a green Lonely Planet Costa Rica guide, about 8 by 5 inches, with a coffee stain on the back edge and light wear on the spine. Inside, there's a yellow sticky note on the title page with the initials 'JL' and a small map tucked between the pages. It looks well-loved but still in decent shape. If this belongs to you, we can meet near the food court to return it.
