At the age of thirty-five, Fanny Van de Grift Osbourne has left her philandering husband in San Francisco to set sail for Belgium -- with her three children and nanny in tow -- to study art. It is a chance for this adventurous woman to start over, to make a better life for all of them, and to pursue her own desires. Not long after her arrival, however, tragedy strikes, and Fanny and her children repair to a quiet artists' colony in France where she can recuperate. Emerging from a deep sorrow, she meets a lively Scot, Robert Louis Stevenson, ten years her junior, who falls instantly in love with the earthy, independent, and opinionated "belle Americaine." Fanny does not immediately take to the slender young lawyer who longs to devote his life to writing -- and who would eventually pen such classics as Treasure Island and The Strange Case of Dr. Jekyll and Mr. Hyde. In time, though, she succumbs to Stevenson's charms, and the two begin a fierce love affair -- marked by intense joy and harrowing darkness -- that spans the decades and the globe.
