THE WITCHES PROPHECY - PART ONE (on hold)

Witches from the age of 21 to 25 can have children with vampires, but there’s a prophecy about a brother and sister of a high power level that will put a stop to this.
Amanda and Dean are said to be that brother and sister, not that they believe that.
Amanda (Daisy to her friends) and her best friend Poppy (an angel) go out the day before her 21st birthday not expecting to see one vampire, let alone three. Amanda’s whole world gets turned upside down as she fights to save herself, her best friend and her brother.
One will survive, one will die and one loses their selves to a dark place.
How will Amanda cope with all that the world will throw at her?
How will Poppy try to save her two live long friends?
How will Dean make amends for the trouble his coursed?
