Revenger is a science fiction space opera that you can’t take too seriously.
There are swaggering captains on ships with sails, raucous crews of misfits who chase treasures. The world is full of islands with treasures, and if a captain has the right maps, or secret information, he can sail to those islands and get the loot. But there are others that will be on his tail and try to take the prize from him. And there are pirates, who board ships, kill everyone and steal the goods. And that is the story. It could have taken place in the Caribbean in the 1600s, but this story takes place millions, or possibly billions of years in the future.
The Congregation is a swarm of “worlds” circling the Old Sun. Worlds are little planetoids, just a few leagues across. It’s not clear what a league is, but I am guessing it’s around a mile. Inside of the planetoids are “swallowers” which I assume to be miniature black holes that generate just enough gravity for the surfaces to be around one gee. There are also spindle worlds, tube worlds and various other exotic ones. Out of 50 million objects in the Congregation, there are about 20,000 inhabited worlds.
And there are “baubles” which are uninhabited worlds with treasure hidden on them, by whom is not clear. And there are space ships driven by ion drives near objects and light sails in open space. The ion drives are like the outboard motors on our sail ships.
Adrana and Fura Ness are two young girls who run away from home and their overbearing father, sign on with a ship, and very soon realize they are in way over their heads. And so the swashbuckling adventure starts.
I realized pretty soon that this is not a science fiction novel, but a pirate novel, masquerading as a science fiction novel. But I did enjoy it sufficiently to keep reading.
