In her past life, Gina Wiseman was utterly drained by her cousin Morgana and a sinister "Wish Exchange System." Reborn with the knowledge of how it works—and the terrible price the user pays—Gina turns the tables. She masterfully manipulates Morgana's greed, luring her into making a series of self-destructive wishes. As the system crumbles and Morgana's mind unravels, Gina must win a deadly game of revenge to reclaim the life, and the son, that were stolen from her.
