5.0

The conclusion to the Above-World trilogy does a nice job of expanding on the world before it shifts into high gear for a non-stop-action conclusion.

The focus on the Upgraders is a nice touch, as (with an exception or two) they'd been the faceless "Imperial Stormtroopers" of the villains in the previous two books. Here, they get faces, culture, and personalities, and they get some of the best moments in the story.

There's extra focus on some of the secondary characters too, as the author expands the perspectives to give a couple of familiar characters their own POV chapters for the first time. Calli particularly shines when she gets her big moment.

There is a theme of separation as the tension builds and the tightly-knit band of friends are nearly torn apart by conflicting missions, loyalties, and issues on their respective home-fronts. But in the end, it's their loyalty for each other that they're going to need to call on in what proves to be a pretty awesome final battle sequence.

This was a solid conclusion with great pacing and a nice resolution and plenty of worldbuilding along the way.
