Koban: The Mark of Koban, Book 2
by Stephen W. Bennett
narrated by Eric Michael Summerer

The first book, Koban, left off with the Krall leaving the captured and tested Humans to die on Koban. After, Par Kur, I probably screwed up that spelling, blew out all the structural protection keeping the native predators away from the his sentient prey why would he bother to think of them after that?
The Mark of Koban shows that humans adapt to survive because we have seldom had natural defenses such as claws and size. Genetic modifications that threaten them with execution if they ever re-enter human space are the order of the day. Blending in exotics hardly seems worthy of mention while throwing out all arbitrary safeguards. The Koban humans take possession of a second dome near the sea they call Hub city which is where all the “shitheads”, my label for the abstainers from the genetic mods are living.
Without spoiling too much, the Primes get a hold of a Krall ship by massacring the crew in hand to hand and close range gun fighting. They secure knowledge of their still being alive after twenty years because “Dead Krall tell no Tales”, Muahahahahaha.
This is a great addition to the series written and narrated with some humor and appropriate shock and awe. Other than the author being hung up on space faring humans using English standard measurements I thoroughly enjoy this series. Yes, feisty aging Maggie is still around thumping Dillon on his cod piece. Four out of five enjoyment points are awarded from me.
