The resourceful captain Sten joins the navy and leads a small group of spaceships in the battle against the Tahn. The genre is a retro space opera with dumb computers and ships that need hundreds of people to be operated.

The story takes a sharp turn from what we saw in the previous three. It is not light anymore, not fun. It’s also not clear where we are heading. Things get from bad to worse with no improvement possible in sight. The problems presented are interesting, relevant, and engaging. The level of action reminds of Ender’s Game but unlike that book, the characters are not juvenile or cringe. It is very intense.

On a philosophical note, the Empire is ruled by an immortal emperor who controls the space fuel, an antimatter molecule that powers the spaceships. This leads to all kinds of bizarre negative consequences that we can see around us in areas where one person or a small group of people keeps monopoly over something. Emperor’s behavior is in a sense similar to what se see from the aging dictators of the modern age, like Xi or Putin, caught discussing plans to live forever, while also slowly losing their minds.

The book was written before the personal computer era really took off. It aged well. It’s not too realistic because Sten shouldn’t have survived half of the action but it got me. Clear 5*/5 and probably the best of the series until this moment.
