She must chase after the only clue they have, a Martian ship called the Phobos, and find out what secrets it hides. To make matters worse, someone still wants her dead.
Her ship, E.S.S. Australia embarks on a mission that leads Serenity on journey of discovery, friendship, betrayal, and revenge. She quickly learns the only thing harder to prevent than war, is love.
Now Serenity must trust her protection crew to keep her alive long enough to solve this puzzle while trying to prevent an interplanetary war.
The line has been drawn. Who will cross first?
