Heiress From Hell

Sera, the true heiress of Vance Airlines, was swapped at birth by a maid and left to fight for survival in a Brooklyn slum. Eighteen years later, she returns to the family fold. Facing the provocations of the adopted daughter Chloe, the favoritism of her mother and younger brother, and the hypocrisy and machinations of her uncle Julian, Sera wields her feigned frailty as a weapon and advances step by step.
