From the back of the book:
In the battle between the Powers of Dark and the Powers of Light, the boreal domain of the Circle of Ice remains aloof. Snatched from your homeland by the Dark Lords, you must spy out the Circle of Ice for them - and return, if you can.
Circle of Ice is third in a series of Pocket Adventures designed for solitaire play with the Tunnels and Trolls game system. To enter the Circle of Ice you'll need a few six-sided dice, paper, pencil, and the Tunnels and Trolls rulebook.
