Lost classic hardcover edition of 'The Great Gatsby' left on a park bench near Stearns Square Park in Springfield, Western Massachusetts.

I last had my favorite book, a classic hardcover edition of 'The Great Gatsby', while I was sitting on a park bench near the Stearns Square Parks in Springfield, Western Massachusetts. I think I must have left it behind while collecting my things. It has my name written on the inside cover, and I'm really hoping to get it back since it holds a lot of sentimental value for me.
