Felicity has never heard of Cinderella, and her life has been nothing like a fairytale. Her mother-who she must call Madam-has kept her locked in a dank basement since she was a young child, giving her nothing but two meals a day and regular beatings. Her only comfort comes from reading, and from the little bit of light that streams in through her small window.

Miraculously, Felicity manages to escape the hell of Madam's creation, and she finds more than she ever expected: Timothy, a young, British artist who captures her heart. Timothy's visits become more and more frequent, and Felicity's world opens up in ways she never could have imagined. He calls her his Cinderella, because she must always return home before midnight, to avoid Madam's wrath.

Timothy isn't the only man who notices Felicity. Just as Timothy walks into her life, a mysterious observer threatens this newly found solace. She is attacked, and discovers, to her horror, how far Madam will go to satisfy her irrational temper. Fearing for Timothy's safety, Felicity tries to remove him from her life. But she soon finds out that their fates are sealed.
