Sci Fi about UFOs

Hey guys! Love this sub and I’ve always found it one of my favourite places on Reddit, especially for reading suggestions.

I’ve always found stories about UFO sighting reports, top-secret government coverups, etc to be really fun to read about. The Roswell Incident has always been a personal favourite for reading about. I just wondered, given there are a lot of really well-versed sci-fi aficionados here, whether there are some good authors and fiction out there that deal with Roswell/UFOs, etc? Thanks in advance!
