The first book was slow to pick up - the first two hundred pages felt like one very long introduction. Only at the last 100 hundred pages did things start happening, but the book ended too quickly for the plot to develop much at that point. I was a little doubtful of the second book at this point, but the first ended on such a cliffhanger that I really had no choice but to read the second. So, I did.
As I discovered, the second book invests a lot more time developing the main characters and advancing the plot. By the end of it, the plot had developed quite well and I was thoroughly attached to the characters in an emotional sense, so the bitter-sweet ending (I won't spoil it any more than that) felt particularly heart-wrenching to me. Honestly, I'm still trying to convince myself that everything worked out in the characters' best interests.
On a separate note though, I'm kind of surprised to find that it was the author of these books who orchestrated such infamous events as the fall of Morrowind, the decline of the Empire, the rise of the Thalmor, and the slaughters in Black Marsh. He did a bit more than just leave his mark on Nirn, I think.
On yet another separate note, I think I may have just lost interest in my Skyrim save file since reading this book. With little-to-no social life and a Highschool education that is now rapidly coming to a close, I'm not sure what to do with myself.
