NEW EDITION: We've changed the design and updated the chapter headings of this exciting and popular book. The last thing Jonah expects is a terrifying wolf-like dog - not in this peaceful Welsh valley, and not on the first day of the school holidays! But worse is to come. Weird creatures appear as Jonah finds himself caught up in an ancient Welsh legend that becomes a modern-day reality. Night Creatures threaten to take over the world and only dragon-fire can destroy them. But the only person who can control the Great Dragon is 12-year-old Jonah.
