This has been a genuinely fun book to have the pleasure to be involved in. We are enormously grateful to the amazing team of authors who brought the text together at very short notice. We hope they are as delighted with the final result as we are and they should be enormously proud of their individual and collective achievements. Their writings have been magically and beautifully brought to life by the outstanding illustrations and exceptional talent of Steve Rawlings. Every book has a team that works with the authors and editors to make things happen. This book would never have come to fruition without the patience and quiet persuasiveness of Joanna Bentley, senior project editor at Ivy Press, and Jane Roe, our copy editor. We owe enormous gratitude also to the design and production teams who made the final book a reality and boy, did they make us look good!
