K.M. Weiland's books are wonderful for anyone starting out on the road to novel writing. Written as if she is talking to you, face to face, her advice and "lessons" have a personal feel. Along with all the excellent information, advice, ideas and guidelines... there is a hint of humour that reminds the reader that writing should be fun and rewarding, despite all the hard work. I believe that these books have given me the confidence and knowledge to take my ideas and start crafting some real stories from them.
