So this is going to be the worst description in the history of any book description ever, but when I was a young teenager I read a sci fi book that I haven't been able to remember the name or author of since. It has been like 15 years and I was a kid so my memory of it is so shakey, but I really enjoyed it and would like to find it again.
It started with a man crash landing on a planet where there is a big order of priests that operate keeping peace in the kind of psychic overworld. He ends up getting sucked into the rescue of one of them and marries her. Since she's married she can't be part of the order any more but she was some sort of royalty so they just go to live with her twin sister and her husband. A good deal of the book is in regards to their relationships and him having culture shock, but at the end they fight some kind of big threat with her psychic powers.
It starts out sci fi but reads like a fantasy book. Anyone who can help it would be greatly appreciated.
