Winter finds herself in a predicament. Sir Martin de Grey has mistaken her for the blacksmith's daughter since she was working in the forge. 

Now, to tell him the truth would risk her friend never seeing his son again. Sparks will fly when the truth is revealed and circumstances turn lovers against each other. But with passion hotter than the fires of the forge between Winter and Martin, can something that started as lust turn into an undying love between them?
