“Streams Of Silver” by R.A. Salvatore. Icewind Dale Trilogy, Book 2. In this book, Drizzt Do'Urden goes with Bruenor Battlehammer to find the home of the dwarves, Mithril Hall. The Dwarves fled so long ago that Bruenor can't remember it's location. With the pair is Wulfgar, but also the halfling Regis.
Regis posesses a powerful persuasive tool, a massive ruby pendant. However, Regis has dae an error; he stole it from the Guildmaster of Thieves in Caliport, Pasha Pook. Pook sent his best assasin after him, Artemis Entreri. I rate this book at 3 stars on a scale of 1-5.
