Yikes!! So Guardians know about the witches. Have they captured them? Is there a spy that knows how to get to the witch portal from the MG pack? This is very bad!
I think it’s time to look into Cassie’s head.
Remember in on of the chapters the guardian was Torturing Jasmine's father. I'm guessing that they want him to speak. And James Grandfather knew about witches
Talia, honey, I know it bothers you to get into another persons head, but I think this is one of those times it is necessary in order to know the truth and be able to protect everyone.
I think it is time for Talia to allow Liselie to work her magic, not just on Cassie, but also on Cassie's dad and James's dad so she can get all information available in order to stop these guys and the guardians before they can do even more damage.
