Lost special edition hardcover copy of 'The Great Gatsby' with a blue cover left in a park in Southwest Michigan.

I lost my beloved hardcover copy of 'The Great Gatsby' while visiting a park in Southwest Michigan last week. I had taken it out to read under a tree and must have left it behind when I packed up. It's a special edition with a blue cover and my name written inside the front page. I'm really hoping it gets back to me.
