Eliza dreams of being a playwright for the king's theater, where she will be admired for her witty turns of phrase rather than her father's wealth.
Beth is beautiful as the day but poor as a church mouse, so she must marry well, despite her love for her childhood sweetheart.
Zabby comes to England to further her scientific studies--and ends up saving the life of King Charles II. Soon her friendship with him becomes a dangerous, impossible obsession. Though she knows she should stay away from the young, handsome king, Charles has a new bride, Queen Catherine, and a queen needs ladies in waiting.
And so Zabby, Beth, and Eliza, three Elizabeths from very different walks of life, find themselves at the center of the most scandal-filled court that England has ever seen.
