Winx: Every move has consequences

What if the Boys cheated on the Winx? Okay, now look, I know a bunch of books about the Winx have this concept, but I promise that this book doesn't have the same ending like the others.
Anyway, "Winx: Every move has consequences" is an idea I've had for a while, and I've always wanted to make it a book, but I'm not the best when it comes to writing, but I'll try my best, so please bear with me. (This book will be a little hard to understand if you haven't watched the series)
