Spirit Warrior

I just finished writing my second young adult, Spirit Warrior. I am typing it now and then will start the editing process. Can't wait to get this one out and have people respond to it. Any opinion on Epilogues in books? I have an epilogue in this book but I took a writing class one time where the instructor told me that prologues and epilogues are used to fix problems with books. I did have a prologue but I abandoned it because the start of the book sounded better without it. I will let you know when the new book is up on Amazon.
