Back to the Heiress, Back to Slay (DUBBED)

Avery Vinton was wrongly labeled as having an intellectual disability when she was six, and her family quietly swapped her out and left her behind. Fifteen years later she is brought back into the household, where relatives who once looked down on her treat her with contempt. Avery sets out to show them that she has real power and stands far above their circle, and even her former boyfriend, heir to the wealthiest family in Eagan, is forced to defer to her. As her hidden identities come to light, she starts to uncover the reasons she was cast aside, reasons far darker than anything she was told.
