These are excellent stories. I just finished all six books and I highly recommend them.
They are NOT super-hero, Good vs Evil intergalactic grand operas. I am as big a fan of the Marvel stuff as the next guy (maybe more). But these books are not about that.
They are novels about normal humans dealing with relationship drama, job stress, management quandaries, what to cook for dinner, coworker betrayals – real life, in other words – against the backdrop of the “Deep Dark” (outer space). But they just as easily could have taken place against the setting of the ultra harsh desert riding in a 1880’s wagon train in the Wild West. Or sitting in a boardroom of a hedge fund in the cut throat 1980’s Manhattan corporate jungle. Or sleeping down in the cramped bunks on a warship in the British navy in the nineteenth century.
That is not to imply there is no science fiction in these books. Extensive sections detail minutia like the inner and outer dimensions of cargo space ships that carry freight from one planet to another. Several key characters in the novels are space ship hardware engineers. Several key plot points revolve around issues like finding elements on different planets, the difficulties in folding spacetime, and the various rulings from the Confederated Planets on Joint Trade. Naturally, all of the action takes place hundreds of years in the future.
If you like that sort of thing, I strongly recommend these novels. They are fantastic.
