The Guardian of the Souls

Julie has disappeared and both Sadie and Kate need to find her, but where to start and how to find someone that just vanished right in front of their eyes is unclear. After destroying the devil and publicly announcing the existence of demons, vampires, and witches, the Sanders Triplets find themselves now split up. Was she kidnapped or did she go willingly? Day by Day, Sadie finds herself gaining the powers of a witch.  For 13 generations there has always only been one witch amongst the triplets, why now does this generation have two? Does this mean that Julie is dead?
