WHAT DOES IT MEAN TO BE A WARRIOR?

The Protectorate of Mars Foreign Legion: A path to citizenship. A fresh start. Defending the Protectorate of Mars against all enemies, foreign and domestic.

HOPE

With itchy feet and a vagabond soul, all Blue ever wanted was to join the Survey Corps and explore the universe. But when she failed the entry exam, becoming a dropship pilot for the Legion was her last chance at achieving that dream. It was only supposed to be a stepping stone . . .

DUTY

All he ever wanted was a home. But when Tavi is driven from his world by murderous revolutionaries, he only has one chance to escape: the Legion. Searching for a new life, he soon discovers something even better—a family.
