When Jasper Jupiter's Circus of Wonders pitches its tent in a poor coastal town, the life of one young girl changes forever. Sold to the ringmaster as a "leopard girl" because of the birthmarks that cover her body, Nell is utterly devastated. But as she grows close to the other performers, she finds herself enchanted by the glittering freedom of the circus, and by her own role as the Queen of the Moon and Stars. Before long, Nell's fame spreads across the world--and with it, a chance for Jasper Jupiter to grow his own name and fortune. But what happens when her fame begins to eclipse his own, when even Jasper's loyal brother Toby becomes captivated by Nell? No longer the quiet flower-picker, Nell knows her own place in the world, and she will fight for it.
