Fullmetal Alchemist, Vol. 3

Accompanied by their bodyguard, Alex Louis Armstrong, the heroes seek out their childhood friend and mechanic, Winry Rockbell, to fix their battered auto-mail body parts. Soon their quest for the Philosopher's Stone takes them to the great central library, where the Stone's formula may be hidden... if the mysterious figure named Lust doesn't get there first! But the secret of the Philosopher's Stone may be even more frightening than the beings who guard it...
