This satisfying sequel to the Cybil-winning middle grade adventure The Fog Diver (2015), picks up immediately where the previous book left off. Following a brief introduction to get the reader up to speed the reader is plunged straight back into the post-apocalyptic world in which the Earth is covered by a sentient Fog made of nanites that are toxic to humans, and people can only survive on mountain tops and in the air above the Fog.
Chess, the fog diver, and his crew have escaped the economically stratified Rooftop and arrived at idyllic and more equitable Port Oro, where they discover that the only way to save the world from villainous Kodoc is for Chess to dive down again to find the mysterious Compass which controls the Fog. Naturally, Kodoc also wants to get his hands on the Compass and is prepared to do anything to achieve that.
It becomes apparent that the crew are more than just a serendipitously well-matched group. Hazel, the quick thinking leader, Swedish, the ingenious pilot, Bea, the preternaturally gifted mechanic, are there to support Chess as his affinity with the Fog means he could be the one to save the Earth. These four characters, plus brawling Loretta, continue to be the warm heart of the story. Though a few new characters are introduced, they pale in comparison and are more plot device than flesh and blood.
The plot is a judicious mix of action sequences and exploration of the world. Port Oro has plenty for the kids to discover and because it is a more fair and just society than that of the Rooftop, it gives Chess a reason to put himself in peril.
Once again there is some entertaining and clever word play on phrases from the old days. Norse is a tapping code used by the Vikings. The Amazons are fierce women warriors who fought battle and sold books. There is a long-running gag with Hazel keeping a Captain’s Log that begins each entry with Start-8. This is smart stuff that is perfectly pitched to be both witty and comprehensible.
The author has made the bold and cheer-inducing move of completing the series in only two books. This keeps the pace fast and the explanations brief, but at the same time doesn’t shortchange the reader. An excellent duology that I would recommend to any scifi or dystopian loving upper elementary or middle schooler.
