For Edward Elric, becoming a state alchemist offers access to military resources that could help him restore his and his younger brother Alphonse's bodies. Their hope rests on the Philosopher's Stone, a legendary object said to magnify alchemical power enough to bypass its central law: every gain requires a sacrifice of equal value.
A year earlier, at twelve, Edward attempted human transmutation with Alphonse to bring their dead mother back to life. The forbidden act cost Edward two limbs and Alphonse his body; Edward saved his brother's soul by binding it to a large suit of armor. Now traveling together in search of the stone, the brothers discover that its secrets extend beyond the power they seek. Their pursuit draws them into the center of a far darker conflict than they anticipated.
