Shanghai 1879 After her sister's successful marriage, Isabelle is sure she'll only ever be an old maid aunt. That is until she meets Langdon. He's tall, he's dashing, and he excites her enough to take a walk on the wild side. But with a month to explore Shanghai before her sister and husband have decreed they must return to England, time is short. Langdon wants Isabelle from the first moment they meet, but with news that she's leaving shortly, he's propelled into action after she makes her proposition. Marriage is the only answer, but he's got other pressing issues. Hunting down the importers of opium and pressure from his superior to see if the Forster sisters are involved. Between the opium problem and issues with running Forster Shipping, Isabelle is learning to accept her sexuality and changed circumstances. It's going to make their first weeks of marriage full of adventure and danger.
