All Flesh by Ananda Devi

A child is born with an insatiable hunger. As a ravenous infant she is the undoing of her mother; under her father's adoring gaze, her body grows and grows. Her father claims she devoured her twin sister in the womb. Her classmates delight in tormenting her for her size. And inside this girl, so alone and so enraged, another hunger is born - for revenge.
