The K-Factor

The K - Factor is a sci-fi story by Harry Harrison, published in 1960. Neel Sidorak and his crew must continuously defend Earth's wellbeing, as Earth had settled quite a few planets in the past and thus made its fair share of enemies. A K-factor is also known as a "war factor", more specifically a name of an atomic file that can be used in two ways, as with an atomic bomb... A thought provoking and engaging listening experience!
