Charlotte Fairfax is asked to travel to the troubled family’s home in Spain to get to the bottom of the mysterious bequest. It’s the week before her wedding but she is confident she has time – there’s only one reason an older man leaves his money to a beautiful woman, isn’t there?

But in Madrid, things don’t go to plan when the woman denies knowing anything about the gift. Is she lying? Looking for clues, Charlotte digs into the prominent family’s history and unearths a dark and shocking past in which two people were torn apart by conflict. But now, their long-buried secrets are starting to reach into the present and Charlotte starts to wonder whether love does not need to forgive or forget in order to endure – but just needs two hearts to keep beating.
