Stuckinavanishingfairytale Stories

I found this book and now I don't know what to do with it. When I found it a mirror and a key came out with it. I found this book in a cave behind a waterfall, when my mom and I were vacationing in the Caribbean for a few days. I showed it to my friends and they all believed my story. Now my friends and I are stuck in separate stories and we don't know how to get out.

Emily, Lily, Dylan, and Kaz are lost in crazy fairy tales and don't know what to do. Meanwhile the stories are beginning to disappear.
