Is Sophie Fevvers, toast of Europe's capitals, part swan.. or all fake? Courted by the Prince of Wales and painted by Toulouse-Lautrec, she is an aerialiste extraordinaire and star of Colonel Kearney's circus. She is also part woman, part swan. Jack Walser, an American journalist, is on a quest to discover the truth behind her identity. Dazzled by his love for her, and desperate for the scoop of a lifetime, Walser has no choice but to join the circus on its magical tour through turn-of-the-nineteenth-century London, St Petersburg and Siberia.
