For the most part this reads like a fantasy. That is, like most fantasies, it takes place in a world and society that functions with a technology of some point in our preindustrial past. I would estimate this one at approximately bronze age. There is no magic though. That might almost make it read like an historical novel except that there is no historical period in the history of the Earth that one could place it in. Instead, it is science fiction. The low technological state is attributed to the loss of civilization by a colony on another planet about three thousand years before. There are barbarians and slavers. There are warring kingdoms and adventure. There are exotic backgrounds and dashing heros. Even though it is technically science fiction that is not made much of a deal for most of the story. Finally, though, the protagonist lays hands on some of the weapons of the lost starfaring civilization and we are reminded of how much of a science fiction tale this actually is. I liked it. Give it a try. You might like it too.
