Answer:
Ooh ok, so you're adding supernatural activity to your story now. Things are starting to get more intriguing :D
Also, I really like Rosa's personality and sense of humor. That's a nice touch to an adventure/thriller story, if I do say so myself.
Explanation:
I'm glad that you added another character to the mix, but you really could've done more with her. Not to mention everytime you add someone to your story, you have to at least introduce your readers to them somehow. For example: how does Rosa know Estella? And where did she get the spell book from? You don't have to go into too much detail with her, if you don't want to, but at least some explanation would be nice.
Hope this helps you, I'll probably even give you more tips and heads-ups in comments, when I can think of more. Either way, keep up the good work! :)
