Changing Currents is the sometimes true story of the war between Tesla and Edison. It is the third in Q's Snake in the Willows Collection and, like his other books, can be read as part of the series or stands alone. While there is absolutely an order to the way these books are written, and they build to paint a bigger picture, each book can be read individually and doesn't rely on on information form the other books to complete the story. This method of storytelling is complex and in the style of works by Terry Pratchett and Stephen King.
