I've not read them myself so I'm not sure exactly where the series starts - you might check on Goodreads or on Salvatore's site for a reading order, but here's all of the Drizzt books we have here:
search.php?keywords=r+a+salvatore+drizzt&terms=all&author=&fid%5B%5D=1293&sc=1&sf=all&sk=t&sd=d&sr=topics&st=0&ch=300&t=0&submit=Search

I believe its Homeland but I would check Goodreads to be sure
