My hubby lost interest in Drizzt at about that same period in the saga. I too love Wulfgar. Who doesn't love the tales of the heroes of Icewindale? My personal fave is Breunor Battlehammer. His story continues long after Wulfgar, and Cattie disappear from the series.
Does this mean you read through the Orc, Pirate, and Ghost King trilogy? If not, I will comment no further concerning the series. I don't want to ruin any surprises, and yes, sorrows for you.
Drizzt, because he is an elf, cannot help but outlive his friends from his past. The current saga is riveting to say the least. And, very creepy, and very dark...
I loved Salvatore's spin-off series, The Sell-Swords. We get to know a lot of very interesting characters in those novels.
