Lost copy of the book 'The Night Circus' with personal notes, left near a bench by the North Platte River.

I lost my copy of 'The Night Circus' down by the North Platte River while enjoying a sunny afternoon. I had been reading it on a bench, and it's possible I left it there when I got up to explore the area. It has some personal notes in the margins that I'd really like to get back. If anyone finds it, I'd be so grateful!
