The dawn of a new century. A mysterious green comet appears in the sky. As the comet draws ever nearer, strange events start to become part of everyday life. The Year of Wonders has begun. People wake up to find a world of marvels outside their window. There’s a troll under London Bridge. Mermaids are swimming up the Mississippi. Is that a dragon trying to hatch the Taj Mahal? And every rainbow ends in a pot of gold. Fantasy is part of the everyday world and nothing will be the same again. But fantasy is a coin with two sides, and there are also age-old nightmares waiting in the darkness to become real again.
