At first, the story seemed almost ludicrous. Our protagonist, Drake Bane, is hard to like and he seems to spend the story making stupid choices, getting hurt, and never learning.
The crew of the spaceship where much of the story occurs are interesting and nicely developed. Even the rogue AI on board has a personality. The universe is controlled by dwarves, but includes elves, goblins, orcs, and a few humans. It's not your typical sci-fi story.
Not all is what it seems. I kept reading hoping things would get better. They did which is a good reason to stick with the story.
The plot involves time as implied by the title. Suffice it to say that much of the inane events in the first part make a lot of sense once we reach the major turning point of the story.
The sci-fi elements are there as background to the story. Even the fantasy beings are mostly part of the scenery.
