This novel contains one of the most bizarre and memorable science-fiction sex scenes I've ever read. (I apologise for going on about science-fiction sex scenes. I read most of my science-fiction between the ages of 11 and 16; other people who have been male teens will understand). Anyway, in this particular book, Gold is some kind of bioengineered asshole supergenius, sort of an artificially created Elon Musk on steroids. Now humanity is under attack from this race of hundred meter tall giants, and they've managed to capture a giant who I think is brain-dead due to injuries he suffered prior to being captured, but is being kept alive in an enormous intensive care unit on the Moon.
So the human generals come up with a daring scheme to infiltrate the alien giants' civilization. They're going to hollow out the captured giant's skull and install a control module there with room for two human operators who will basically act as puppeteers and run their host by remote control. Then they'll arrange for the giant to be found by his fellow-aliens, and for some reason the control module won't immediately show up on the first X-ray they do, cuz stuff. The original plan was for the lead puppeteer to be another bioengineered supergenius who's a whole lot nicer than Gold, but he's killed at the last minute in a freak accident. Asshole Gold is persuaded to take over - the puppeteering job, as you can imagine, is incredibly difficult, and no ordinary human could do it. He has this chick as copilot who I think might have been the girlfriend of the other bioengineered supergenius. She doesn't like Gold much.
The whole thing goes according to plan, and the aliens accept the living Trojan Horse as their comrade, who's had a miraculous escape. They head off back to the giant alien planet and the alien is reunited with his wife. She thinks he's weirdly changed, but, well, he suffered some bad head injuries and perhaps he hasn't recovered yet. One night she decides she's going to have sex with what she believes is her husband. Gold, who's running the show as usual from his seat inside the alien's head, manages to make everything work well enough that the wife is fooled. He finds it incredibly arousing. When they've finished, and the wife is dozing off into satisfied post-coital slumber, he gets up, goes back to the cramped sleeping quarters, and rapes his copilot.
They shouldn't let impressionable fifteen year olds read this stuff. I'm sure it isn't good for them.
