The Swamp Daughter

Lilian Devereux was drowned in the depths of a swamp by her adopted sister's boyfriend, who was also the son of a powerful figure in the town, under the guise of "purification." But no one expected that she would make a blood pact with the serpent god at the deepest part of the swamp: to exchange all her emotions for a rebirth as a vengeful being. Seven days later, she walked back to the town covered in mud.
