Review Detail of RiverBlue in Universal Mercenary System

I am not used to write reviews on the stories I read but I will make an exception for this one , This story is great almost an hidden gem ! Their is a system but not the usual and cliche one , the characters and the main one are very uncommon I like this story too because of the unusual type of world, this is a grey-dark world where everything is clearly not all pink I really want to read more to see the development of the characters and the evolution of the novel !
