"Troll Song aims to tell the story of trolls as a people, a culture, a society. The trolls are under threat of extermination, but although they're big and strong, these trolls are no mindless brutes - they are a simple but honourable people with their own sense of morality and honour; a people who have feelings, who develop friendships; even a people who make music. Well, a sort of music... For the four trolls who manage to survive the attempted trollicide, it's not simply a matter of staying alive, or even a matter of revenge - for you see, to find out what their future can be, they first have to learn about their history - the very origin of their race.
The trolls find a secret laboratory. New understanding is about to come their way... and a new quest.
