Executioner's Gambit

Fantastic job, Mr. Luterman! I mean, what with the overflow of mysteries of all kinds, science fiction included, THIS book stands out for the vibrancy of its story, the carefully developed plot, the secondary tale, the characterization, the fine art and worldbuilding... Everything will keep you glued to the pages without a moment of boredom!
The best part is how the ambiguity plays a role in defining the characters -everyone here is motivated by selfishness and the same main protagonist is not exempt! And yet, when it comes to giving the spotlight, we understand that people is not supposed to be all-good nor all-evil.
Everything happens inside a 10.000-crew generational ship. No one can get out. And you would neverf expect what happens after it's clear there's a serial killer aboard. THIS is a mystery! I WANT MORE!
