The Calling by David Gaider
Story-wise, this wasn't as good as its predecessor, with a somewhat shaky plot pushed a long by the questionable motivations of the characters. Fortunately, it was the characters that made me want to read these books in the first place in order to learn more about them, and Gaider again delivers, with the focus, this time, on Maric and Duncan. He adds a load of depth to both characters, making me love them all the more and feel for them and those that come after.
I also like Gaider's grasp of battle writing. It probably helps that I've played the game these books spawn from, but I think anyone else would appreciate and be able to visualize the battles and how each character moves and flows within them. Playing the game means you can actually visualize the commands used by the PCs and NPCs in game.
