Book number two of a eight book science fiction space opera series.  I reread the well printed and well bound POD (print on demand) trade paperback self published by the author in 2018.  I have all eight books in the series and am rereading them now with the number seven and eight books that I just bought from Big River.
Wow, great story with lots of character development and action.  An older engineer buys a bunch of Nikola Tesla's journals in an old chest and spots a design for an "electric turbine" that was never built.  He builds a working version of the electric impeller (a device that converts electricity into motion) after many restarts and has an anti-gravity device.  The rest of the story concerns project funding and building various containers for the electric impeller and various peoples trying to steal the design.
The book starts with NFI has spread itself across Earth into smaller countries like Finland and Japan after getting run out of the United States.  NFI has totally left the land and sea businesses and is strictly focused on the space business.  They have built several space ships now and are moving to a bigger class of space ships capable of carrying a multiple ton cargo plus a larger crew.  Travel back and forth to the Moon is common now for NFI space ships but very people on Earth really understand this.
The writing of the story is a little bit rough, a little more editing would have been good.  But for me, the story is always the most important thing.  This is my second read so that makes it a five star book for me.
BTW, this is not the first time that a story has been written similar to this.  Several stories have "magical" engines for space drives.  A very similar book is John Varley's most excellent "Red Thunder" which uses the squeezer drive.

The reason why I like these stories so much is that it is not just the new drive device, it is also the design and work to build the container around the new device.
My rating:  5 out of 5 stars
