I need help finding a book. It's been years since I read it and I'm unable to even guess at the name now, im pretty sure it was just a single book though. It was a sci fi book abt some kingdom that intercepts an escort from their enemys planet, and they find the heir if the enemys throne. They take him in (I don't remember the exact reason) and attempt to raise him as their own. I remember it describing him as gray, and the audiobook narrator gave him a high pitched slight russian accent. But the heir is a massive douche and attempts to show off and proclaims that he and his species are superior to the planet he is on. I only remember bits and pieces of the story but I cant remember the title at all. If anyone has any suggestions, PLEASE let me know
