My mom read a book years ago when she was in high school (around 1980s) and she's been looking for it for years. She claims the name of the book is The Derby and it's a book set in the early 1900s about a young girl. She never specified whether or not it was a romance but it is about a hat (hence the name). I was wondering if anyone knew who might have written it or perhaps if anyone knew where I could get it. I tried searching on Amazon but I've had no luck. I would love to get it as a present for my mom's birthday. Thank you in advance!
