San Francisco, 1915. As America teeters on the brink of world war, Charmian and her husband, famed novelist Jack London, wrestle with genius and desire, politics and marital competitiveness. Charmian longs to be viewed as an equal partner who put her own career on hold to support her husband, but Jack doesn't see it that way...until Charmian is pulled from the audience during a magic show by escape artist Harry Houdini, a man enmeshed in his own complicated marriage. Suddenly, charmed by the attention Houdini pays her and entranced by his sexual magnetism, Charmian's eyes open to a world of possibilities that could be her escape.

As Charmian grapples with her urge to explore the forbidden, Jack's increasingly reckless behavior threatens her dedication. Now torn between two of history's most mysterious and charismatic figures, she must find the courage to forge her own path, even as she fears the loss of everything she holds dear.
