The Frost Alchemist

Levy's life was never ordinary. From the time that she was seven to when she was eleven she raised her younger sister, that is until her sister dies. Overly grieved by her sister's death, Levy performs the ultimate taboo in alchemy: human transmutation.

After crawling out into the snow, bleeding from her lost limbs the Briggs soldiers find her and help her with the help of the Elrics. Levy becomes a soldier once she's healed and when an old friend asks for help that will take her away from Briggs, she accepts. Not long after reaching Central, her talent with alchemy is discovered and she is made a State Alchemist by the Fuhrer himself.

She soon discovers a secret that had been covered up for years, it's a secret that should have been dealt with when Edward was still a State Alchemist, but now it's her job to put an end to it before it destroys Amestris.
