Fullmetal Alchemist (3-in-1 Edition), Vol. 6

In an alchemical ritual gone wrong, Edward Elric lost his arm and his leg, and his brother Alphonse became nothing but a soul in a suit of armor. Equipped with mechanical auto-mail limbs, Edward becomes a state alchemist, seeking the one thing that can restore his and his brother's bodies...the legendary Philosopher's Stone.

The Elric brothers head north to Fort Briggs in search of May Chang, whose Xing alchemy may contain the answers they seek. But as Ed and Al soon discover, the only thing less forgiving than Briggs's weather is the regiment of hardened soldiers assigned to defend it. Matters grow even more complicated when Ed and Al get thrown in lockdown and the sadistic Kimblee arrives from Central with Winry as his hostage. But even Kimblee's cruelty pales in comparison to the evil of the new homunculi watching from the shadows...
