The Crystal Shard: Icewind Dale Trilogy #1 (Legend of Drizzt #4)

Drizzt Do’Urden has settled in the windswept towns of Icewind Dale. There, he encounters a young barbarian named Wulfgar, captured in a raid and made the ward of a grizzled dwarf name Bruenor. With Drizzt’s help, Wulfgar will grow from a feral child to a man with the heart of a dwarf, the instincts of a savage, and the soul of a hero. But it will take even more than that to defeat the demonic power of Crenshininbon, the fabled Crystal Shard.
