Synopsis:
The Republic and the Mandalorians are at war! Jedi are joining the fight, despite the noninterference stance of the Council. One Jedi, however, has found himself on the front lines against his wishes—the peace-loving Zayne Carrick has been drafted!
The Mandalorian Wars heat up as this new series about the Old Republic takes off!
Can a pacifist survive in a war zone? Jedi Zayne Carrick is having a hard time of it, first drafted and now caught in the crossfire between the Mandalorians, the Republic Navy—and even fellow Jedi!
Peace-loving Jedi Zayne Carrick is an unwilling recruit in the war between the Republic and the Mandalorians. When he discovers that his homeworld is about to become the center of a battle zone, Zayne is prepared to do everything to prevent bloodshed - like calling in a favor from an old friend and putting together a complicated ruse!
The battle for the future of the Republic is on!
The Republic, the Mandalorians, and even some of the Jedi are corrupt—so Zayne Carrick is going to take matters fully into his own lightsaber-wielding hands. It's high risk and utterly insane, and the allies Zayne has to work with aren't exactly what you'd call trustworthy...but at least this time he knows that up front!
Part one of Zayne's plan to foil the Mandalorian Knights and their misguided leader is complete - but the battle is not yet won. Taking on the Mandalorians face to face is still on the agenda, and Zayne's questionable team could blow the operation at any moment...With everything on the line, all Zayne can do is have faith!
