The main character’s something of an ass (admittedly, this is part of the story, so at least he’s not an ass for no reason), but the general conceit and worldbuilding is fascinating. Humanity has found the remnants of an alien race, including a fleet of FTL ships…but nobody really knows how to work them. Take one out and you might come back with treasures worth millions, you might come back with nothing, you might come back dead, you might not come back at all…and the odds aren’t in your favor.
