Soul Eaters

Vampires do not exist.

What does is much much worse. Vampires only take your blood; these creatures take your soul.

Nicholas is the most powerful soul eater ever to have existed, surpassed only by his father, whom the witches captured centuries ago. He requires one more person to sacrifice in order to bring his brother back into the world. When he chooses a woman who no longer has anything to live for, it affects them both in ways neither of them could have imagined. 
John and Emma were looking forward to starting university until their world was turned upside down. Now two of their friends are dead and they have discovered that their mother was a witch, a member of a coven which has vowed to hunt down and kill all soul eaters.
Will the twins choose to forget all they have learned or are they brave enough to face Nicholas and his family and destroy them before they enslave mankind? And what will the witches do when they discover they are facing a threat far worse than they ever thought possible?
