It's been two years since Maewyn discovered her magick and saved the Wedge from a troll invasion. Now the hapenny villagers are embarking on an age-old tradition that was given up after the first troll invasion: A Great Expedition. This is a chance for the younger hapennies to discover the world outside of the Wedge. But the world outside of the Wedge can be a scary place, and the hapennies soon find themselves knee deep in troll trouble.
