Is this the end of the story? Looks like there are a few more things to wrap up and a conclusion to give the characters some closure.
Again, the first thing I noticed is that this seemed very rushed. If you were trying to write this story in a certain number of chapters I'd say you were a bit ambitious with the size of the story you were telling. If you plan to keep writing or didn't have a set amount of chapters I'd say just take your time and flush out your scenes rather than trying to rush to the action right away.
It felt like there was no build up to the climax of the story. The witches were introduced as these powerful characters then basically got one-shot. An explanation would be nice, either in the build up to the attack or soon after. It felt like the conflict overall was just solved too easily and I didn't get to connect with the struggles of any of the characters, or even get to know them.
Also, how was Missy just welcomed back and on the good guys side all of a sudden? Did she have some revelation or change of heart?
The only really noticeable spelling mistakes were a missed ( in the first paragraph and this line "Then she fainted dead away." What were you trying to say there? If you were using dead to describe the way she feinted it was a bit confusing.
Overall though, I was able to follow the story quite easily even if I felt there were a few details missing, and I enjoyed the revelations and action scenes in this chapter.
