The Crystal Shard

Dungeons & Dragons hero Drizzt Do'Urden finds new friends and foes in the first book of the iconic Icewind Dale Trilogy.
With his days in the Underdark far behind him, drow ranger Drizzt Do'Urden sets down roots in the windswept Ten-Towns of Icewind Dale. A cold and unforgiving place, Ten-Towns sits on the brink of a catastrophic war, threatened by the barbarian tribes of the north.

It's in the midst of battle that a young barbarian named Wulfgar is captured and made the ward of Bruenor, a grizzled dwarf leader and a companion to Drizzt. With Drizzt's help, Wulfgar will grow from a feral child to a man with the heart of a dwarf, the instincts of a warrior, and the soul of a hero. But it will take even more than that to defeat the corrupt wizard who wields the demonic power of Crenshinibon--the fabled Crystal Shard.

The Crystal Shard is the first book in the Icewind Dale Trilogy and the fourth book in the Legend of Drizzt series.
