The Huntress and the Spartan by red october700 reviews
Two years adrift in the middle of nowhere. Two years of doing nothing. When a sudden wormhole appers and sucks the DAWN into it, it spits them out over a crazy new world. A world with it own problems that may need a SPARTANS helping hand. This is my first story. Expect mistakes, and this is only part one of a three way crossover. Constructive criticism is welcome.
