She never intended to meet her fate anywhere other than on the battlefield, and her peaceful demise has her wishing desperately that things could have been different... But when she suddenly comes to in the body of the young, frail Nia Liston, she’s got an all-new fight ahead of her. Nia is a sickly child, meaning she has a long way to go before she’s in fighting form.
