I’ve tried to find this book for the last thirty years. It’s an old sci-fi novel.
What I remember of the plot:
Advanced insectoid winged aliens invade earth, they are very random and do things like cure disease and pour wealth from spaceships in one city, and then fire bomb/laser death another.
Hero is ex government something, like a soldier or bodyguard like secret service.
He ends up at some point at a rebel base where they are trying to fight the invaders, but are wounded and starving.
He gets captured by the aliens, and is enslaved by one of the very high ranking aliens, a Princess or equivalent, who is spoiled rotten, vain and very cruel. She has a sort of partner who is a warrior, but she outranks him and treats him badly.
They talk, but also use dancing like bees to convey extra texture to the conversation, she mocks her partner/mate because he is not graceful when “talking” by dancing.
She ends up trying to bang the human out of boredom, which is painful for him, and he jumps off her floating ship/palace to try to kill himself after suffering at her hands for a while.
She makes her mate/fiance fly to rescue him, but he signals that the price he will want in return will be terrible.
At some point she is stripped of power and exiled.
She meets the hero at a rebel camp some time later, and she has been de-winged and blinded by her kind.There is a church of anti-Christ that has something to do with what is going on.
Alien princess becomes a Christian.
