Hot Martian Girls

Two centuries in the future, Earth farm boy Grayson Leganna emigates to a newly-independent Mars. Trying to make a living among its growing colonies, he ends up on a months-long mission alone with three young Martian women. The genetically-engineered ladies are slim, blue-skinned, and considerably taller than their normal human crewmate.

As the mission grinds on, tensions rise, but so do unexpected passions and romance. Mars is far from the only new frontier Grayson ends up exploring with his new companions.
