A deeply empathic exploration of obsession and art, genius and madness. . . . Morgan's ability to bring each character to life is virtuosic. --The Washington Post Book World In 1827 Harriet Smithson, a beautiful young Irish actress, determined to avoid the traditional route to stardom via the manager's bed, joins an English company in the bold experiment of taking Shakespeare to Paris. With the ferment of revolution in the air, the new generation is longing for passionate, spontaneous art. And to Harriet's astonishment, it is embodied in her--La Belle Irlandaise. In the midst of this frenzy she finds herself pursued by a strange, intense young composer named Hector Berlioz. So begins a painful and profound love affair. She is his muse; his idée fixe; his obsession. And Berlioz's Symphonie Fantastique, directly inspired by Harriet, will change music forever.
