Blade of Ulvinter

Publisher's blurb: Blizzards scream down through the mountain passes of Icewind Dale for weeks on end, blocking roads and forcing coastal ships to port. Winters in Icewind Dale are known to be cruel, but never this early in the season and no one has heard of a storm lasting this long. What sinister force is causing these unnaturally brutal gales? Will they ever subside long enough for Northern towns to gain the supplies they need to avoid starvation?
