Gundam Seed, Volume 4: Mobile Suit Gundam

MISSING IN ACTION

Devastated by the cruel realities of war, Flay, Athrun, and Miriallia grieve, believing that Kira and Tolle are dead. Even as they mourn and question themselves, the fighting intensifies. Coordinator leader (and Athrun's father) Patrick Zala gains political control over the Plant, and the battle between Zaft and the Earth Army shifts to a military base. When the crew of Archangel realize that Earth has used them as bait and betrayed them, they decide to embark on a journey to the neutral state of Aube to start new lives. But on the horizon are new, more powerful mobile suits that may just turn the tide in this war!
