The superpowers of the Solari are science-based; exposure to trarium. The school has cool tech like the VR/AR HOME, as well as the transports the kids use, jet and car both very souped up, not to mention the tech that one of the kids creates. It's a relatively standard plot; kids save the world, but the culture and setting in Nigeria give it a different spin. This is the third in a series, but it took me a while to realize that, I feel that this book could stand on its own. The mechanics of the world and past happenings, are explained well enough and smoothly enough that they aren't disruptive to understanding the story. I appreciate the pronunciation guide, glossary and guide to Pidgin which were in the back. I liked the different abilities the kids had; Adanna's tech and empathy which are usually opposites, and I loved that Onyeka's superpower was her hair. I want to see good science fiction like this which also showcases different cultures. I also appreciated that as much as the kids have these superpowers, they are still kids, and treated as such much of the time.
