Star Traveler: A scifi harem

Drake Neely thought he was destined to be a hero. Turns out, he was right. 

As an Ensign in the Zion Fleet, Drake is reminded constantly of his father's heroics. A decorated war hero and leader of the Fleet, Polemarch Neely has made Drake an Ensign as he trains for "bigger" things. 

But Drake thinks he's ready to step up now. 

When his father sends him to investigate a disturbance on a barren planet, Drake finds himself pulled into a new world - a world that depends on him to be the hero he always believed himself to be.
