A great big thank-you is owed to Eric Walters, who thought up the whole series and wrote the first book; to Andrew Wooldridge, who said yes; to Sarah Harvey, who kept track of all the fictional characters, all the authors, all the timelines and all the details; and to Shane Peacock, John Wilson, Ted Staunton, Sigmund Brouwer and Richard Scrimger, who wrote the other books in this series.
