I'm going to have to go with Icewind Dale. I love Salvatore's earlier writing. I see Song and Swords ranking quite highly, and I'll have to check that out. One of my problems with many of the Realms novels I have read (and Dragonlance as well) is that the writing is sub-par and cliche. I'm looking for something to break that trend.
I've gone with the Finders Stone Trilogy. Though you get the impression half of those ones were never planned as trilogies at the start, but the first books were too popular.
Ie. my favourite 3 FR books, that when I've read what I've got and short of cash for something new I can re-read happily for the 37th time are 'Azure Bonds', 'The Crystal Shard' and 'Pools of Radiance'. I don't feel compelled to finish the trilogies when I do. Where as if I read something like 'Return of the Archwizards' or 'Avatar Trilogy' stopping at book 1 really can't be done.
