This book gives clear explanations on how to improve the dialog in your novel. There are scores of examples and each chapter has exercises to reinforce the points.
“As an editor, I wish all my clients would read and apply the advice in this book. James Callan describes the writing of dialog in simple terms … easy to grasp and apply. He even includes exercises … Highly recommended for anyone who attempts to write dialog.”
— Lorna Collins, content editor & multi-published author
