It's not at all uncommon for the author of some really trite and cliched piece of work to say, in an interview, "This is the story I was born to tell. The characters just really spoke to me, and they would not allow me to rest until I wrote this book."
Meanwhile I'm sitting there being like...really? This book? The Tolkien clone that I just read?
