Elfshadow - Elaine Cunningham First book in a series set in the D & D world of Forgotten Realms.
Really well written, featuring interesting characters and a good murder mystery plot running through it.
The story moves at a good pace, with the heroes picking up clues here and there as well as hints about the background of the main character, Alisa Moonblade.

Probably one of the best D & D books I've read in a long time, and will be looking for the next book in the series to see if the author can keep it going.
