From publisher blurb:
Long past are the days when drow ruled over Shadowdale from the Twisted Tower—or are they? Beneath the sleepy farming community, an old evil stirs. The drow and their foul Underdark minions have set eyes on the Dalelands, but to what end is anyone’s guess. Now, it’s up to an unlikely band of adventurers to defend Shadowdale from the drow threat and learn what Lolth and her villainous followers are up to. Success means a respite from danger. Failure could doom the surface world.
