Starless Night: Legend of Drizzt: Legacy of the Drow, Book 2

The Underdark. A place of brooding darkness, where no shadows exist, and where Drizzt Do'Urden does not wish to go. The noble dark elf must return there, though, he must go back to find his friends in the gnome city of Blingdenstone, and on to Menzoberranzan, the city of drow. Only then can Drizzt discern what perils might reach out from that dark place to threaten his friends in Mithril Hall.
