When I was rather young I had picked up a bunch of SF books at the library, one had a kind of interested plot about an undercover Space Cop of some sort who had somehow been turned into a slave.
It might have been part of a series. The main character was female and she had some sort of pain / pleasure implant. She had been turned into the slave of some sort of Space Pirate whom she was intent on bringing to justice or something.
It was rather a graphic book, both sexually and when it came to violence. It also wasn't what you would call well written. Though at the time the idea of a future with some sort of Space Patrol going undercover to capture Space Pirates had fascinated me.
Recently someone mentioned the same book and neither of us could remember its name.
We were both pretty sure it was written in the 80's or 90's and most of it took place on a space ship where the girl was kept hostage. We think that the Pirates hadn't known she was an undercover Space Cop and she may have been drugged and implanted with this device. She might have been a crew member at first (maybe an engineer) that the Captain turned into a slave, we're really not sure about that. We can't even remember how it ends for sure...
Can anyone help us?
