After surviving the rigors of Ellis Island, Maureen learns that their benefactor, Colonel Wakefield, has died. His family, refusing to own his Civil War debt, casts her out. Alone, impoverished, and in danger of deportation, Maureen connives to obtain employment in a prominent department store. But she soon discovers that the elegant facade hides a secret that threatens every vulnerable woman in the city.
Despite her family's disapproval, Olivia Wakefield determines to honor her father's debt but can't find Maureen. Unexpected help comes from a local businessman, whom Olivia begins to see as more than an ally, even as she fears the secrets he's hiding. As women begin disappearing from the store, Olivia rallies influential ladies in her circle to help Maureen take a stand against injustice and fight for the lives of their growing band of sisters. But can either woman open her heart to divine leading or the love it might bring?
