Query: Couldn't put the book down!!!

A few days ago, a friend recommended this book to me. She said it was good and worth a read. So, I picked the book up and began a great journey. This book was similar to "middle earth" and other fantasy sagas, but it wasn't exact. I was enthralled by the imagry of the book and the characters. The second book better come out really soon, because having to put this story off until it comes out is excruciating to me. Same as with the Harry Potter series, I don't want to have to wait three to four years before the next book comes out. When reading those books, I couldn't help but notice the similarities of Harry Potter to The worst witch. Although, I enjoyed Harry Potter much more and feel it is much much better than The worst witch.Christopher Paolini better put the second book out soon, because my reading glasses are itching to be put on.
