Fullmetal Alchemist (3-in-1 Edition), Vol. 7

Contains volumes 19, 20 and 21! The story enters its final stretch as the Elric brothers learn of the homunculi's ultimate plan to turn all of Amestris into an alchemical bloodbath on the Day of Reckoning. While tempted to use the open portal that day to get their bodies back, for now the brothers build opposition to the homunculi-corrupted military with others who have learned of the grisly plan. While Al learns the secret of the homunculi's origins from his father, Ed joins forces with a familiar homunculus who seems to be having pangs of conscience.
