As Cécile exits a crowded showboat after enjoying a lavish Floating Circus, she stumbles--and when she gets up, she realizes that the cameo necklace she borrowed from her aunt is no longer on her neck. Knowing that the necklace was the last gift Tante Tay's husband gave her before he died, Cécile is desperate to find it. As she tracks down the people in the crowd who were near her when she fell, her search takes her into many corners of New Orleans, from a society tea party to the crowded French Market, even the dangerous cypress swamps...and deep into secrets she never imagined! An illustrated Looking Back essay provides facts about the 1850s.
