Sister by Name, Guardian by Choice

Claire Carter, Carter family heiress, learns her so-called sister Blaire Carter is not her biological sibling. Her real sister Sophie was swapped at birth and endured years of abuse. Claire takes timid Sophie home, helps her grow and reclaim her identity, fending off schemes from the fake sister. Digging deeper, Claire finds her great-uncle masterminded the swap. She foils his plots to harm Sophie, protects her sister, and brings him to justice.
