Daniel has spent centuries falling in love with the same girl. Life after life, crossing continents and dynasties, he and Sophia (despite her changing name and form) have been drawn together-and he remembers it all. For all the times that he and Sophia have been connected throughout history, they have also been torn painfully, fatally, apart.

But just when Sophia (now "Lucy" in the present) finally awakens to the secret of their shared past, the mysterious force that has always separated them reappears. Ultimately, they must come to understand what stands in the way of their love if they are ever to spend a lifetime together.
