Twins should never be separated.
Aurelia and Marguerite never had a chance at normality. Their parents are vampires. The blood of an immortal deity runs in their veins. And they've been traveling through time since before they were born.
But now there are strange whispers coming from an ancient fountain in Spain's Alhambra Palaces. Voices calling from pathways to the past that are mysteriously closed.
Voices that haunt their dreams, and tug at their hearts.
Aurelia gave up on love a long time ago. Marguerite has never stopped looking for it.
Now love has found them both.
Impossible love.
Love which threatens their ability to find one another again - and to find their way home.
