Any way to preserve this flower?

My grandmother passed away recently, she was a big part of my life and it’s painful. During her funeral service this one rose slipped off of her casket and fell. I’m not religious or superstitious I don’t think that it was my grandma but I do feel like it’s special. I’ve kept it alive as long as I could but it won’t last forever. I want to keep it, my first thought is to press it a book but I’m hoping someone might know a decent alternative.
