From the back cover:
Winter's chill spreads across the lands of Ansalon even as the Dragonarmies continue their terrible war. Dragons of many colours seem all but unstoppable, and the legend of the dragonlance seems little more than a child's bedtime tale. The heroes must continue their journey to unite the free nations in a war against the armies of the Dark Queen and find the keys to fighting evil on equal footing. From knowledge gained in the ancient port city of Tarsis and the frozen tundra of Icereach, to the legendary stronghold known as the High Clerist's Tower and the doomed city of Sanction, the companions might find powerful weapons and lost relics ... and perhaps the answers to age-old questions.
Dragons of Winter is a DRAGONLANCE® adventure for the d20 System set in the War of the Lance era.
