Soul made of Asphodel (M)

When Lord and Lady Peverell summoned Death to bring them the resurrection stone for safe keeping they not only destroyed one of Voldemort's horcruxes but bound their unborn child as Death's soulmate. Persephone Peverell grew up knowing she would become the next Mistress of Death. Helping the boy-who-lived, Persephone embraced her future with Death, instead of fearing it.
