A Chance of Rayne — Suzanne G. Rogers

Although the Harrison daughters look almost like twins, one was born on the right side of the blanket while the other was not. Rayne is tasked with drawing in a suitable husband for her sister, Garnet, but soon discovers her quarry is a kindred spirit from her past. When Rayne refuses to deceive Lord Finch any longer, her father makes good his threat to exile her overseas, to New York City. Although Rayne is determined to survive, she is quickly ensnared in a web of vice.
