Isabelle Beaumont is a young, intelligent girl living in a small French town. With her father as an inventor, she lives a fairly comfortable life - with one glaring exception: she doesn't remember anything that happened before her sixteenth birthday. Adam Lancaster is a forgotten prince. With a castle overrun by thorny bushes, he lives as if he is in exile, accompanied by only a few of his trusted servants. When Isabelle and Adam meet for the 'first' time, Isabelle realizes that perhaps it isn't really their first meeting - five years ago, she turned the prince to a beast, after all.
