Writing a book is hard!

Have you ever tried to write a book or story and have it come together in your head, but once you try to write it down it doesn't make any sense? Well rest assured you are not alone. You see right now I'm in the process of writing a book called Dawning Rose. Its about a teenage girl, Faeries and love. I had the whole book planned out and everything in my head but when I went to go write it down it didn't look right or sound right. So world of book lovers I am pleading on my knees for you to help me and send me feedback about what I should do or who I should try to talk to about my book. Because right now it is in the form of 'completely sucky story'.
