"Damnation has never been so sweet... When Rosamund Tomkins enters the world she is so different, with her darkling eyes and strange laughter, that the midwives are afraid, believing her a changeling. But Rosamund's life is set to be anything but enchanted... Born into poverty, brutalised and ignored by her family, it is only when she is married off to a nobleman that her life undergoes a wondrous transformation, as he recognises that Rosamund infuses magic she does not know she possesses into everything she touches. Clever, quick and irrepressible, Rosamund soon becomes the darling of the haute ton, and presides over her luxurious chocolate house where the rich go to be seen and indulge in their favourite pastime, drinking the sweet and heady drink to which they've become oddly addicted. But Rosamund stands on the brink of losing all she has worked so hard to achieve and will be forced to make a choice: walk away from all she knows and has grown to love with her soul intact, or make a deal with the devil?"
