Overview
In the final book of the #4 New York Times best-selling Neverwinter Saga, Drizzt Do’Urden navigates a winding path littered with secrets and lies. Tangled up in his companion Dahlia’s dark secrets, the ties that once held her close to Drizzt threaten to tear as her bonds to his former foe, Artemis Entreri, continue to grow. Meanwhile, in the caverns of Gauntlgrym, the drow Tiago Baenre enlists the help of Bregan D’aerthe in his quest to destroy Drizzt. While making promises they may not keep, the agents of the elite drow mercenary group hide plans of their own. Determined to stand for what’s right in the Realms once again, Drizzt forges a new road north—toward Icewind Dale. Will his new companions follow? Can he fight the darkness alone? Either way, he knows now where he’s headed—back to the only place that’s ever felt like home.   
 
 
Praise for the Neverwinter Saga:
 
“Emotional, respectful of its characters, intelligently written and structured, and finally summons a sense of nostalgic sorrow throughout”–Fantasy Book Review on Gauntlgrym, Neverwinter Saga Book I
 
“Full of excitement. Salvatore has mastered the art of showing a beautiful fight scene, and he is at the top of his game in this one. We meet many characters with many different fighting styles, and Salvatore does a great job of distinguishing between them. He manages to take these scenes from so much more than just a fight scene, to an integral part of the story.”—The SFF Hub on Gauntlgrym, Neverwinter Saga Book I
 
“A quick read with some very satisfying fight scenes. It’s also deeply layered with emotional atmosphere” —California Literary Review on Gauntlgrym, Neverwinter Saga Book I
