Algae and toe shoes, feathers and tutus

Behind the gilded doors of the Paris Opéra Ballet, two best friends, Madeleine and Lucie, dance the night away. But at first morning light, their human bodies transform into webbed feet, billed lips, and wings.
When enchanted, the girls are the Bois de Boulogne's famous black and white swans. For ninety years, they have floated in the lake, unable to find true love and break the evil Dance Master's curse. But when Madeleine meets American transplant Zig Young, everything changes.
Suddenly, Madeleine wins a coveted solo spot in an upcoming ballet, and her growing relationship with Zig means she's on the verge of breaking the enchantment. However, doing so means leaving the Bois, the Ballet, and Lucie forever—something she's not sure she can bear.
Desperate to not lose her best friend, Lucie will do anything to keep Madeleine with her—including betrayal. She'll stop at nothing—even if it means breaking Madeleine's heart and dooming her to life as a swan forever; even if she ruins her own chance at happiness.
In this retelling of Swan Lake, the lines of good and bad blur as Madeleine and Lucie struggle to choose between the lives they desire and the friendship they crave.
