Lost hardback special edition of 'The Great Gatsby' with a blue cover at Hilton Head beach.

I lost my hardback edition of 'The Great Gatsby' while lounging on the beach at Hilton Head. I remember setting it down next to my towel and when I finished a swim, it was gone. It's a special edition with a blue cover and my name written in the inside cover. If anyone finds it, I would really appreciate its return!
