Cosmic Fire (The Mars Academy Series Book 2)

Ensign Dana Lawson of Sector Seven fire team on the star ship, Columbus, has one goal: her own command. On an exploratory mission to Alpha Centauri A, she has the opportunity to earn her stripes, but instead faces a challenge that threatens to send her plans up in smoke.
Rick Morgan, a guy with heartbreaker imprinted in his DNA, the warmest smile and the bluest eyes she’s ever seen, ignites a fire inside her heart. He is trouble, on every level…and he’s brought his dangerous past with him.
Now a saboteur has Dana and Morgan in his sights. Together, they must learn his identity before he strikes again and kills them both…or destroys the ship and everyone on board.
