This book brings an end to the trilogy started with the Rage and the Rite. This is one of the the better series to come out of the FR novel line, and I particularly enjoyed the first two. But this one disappointed slightly, especially at the end.
Firstly, a few pretty heavy-hitting figures in the FR mythos get wasted, almost in passing, and it doesn't really feel like much of an event when it happens. When someone (I'm not saying who) has statistics in the Epic Level Handbook, you really think that their death should be quite important and difficult to achieve, and maybe even a key element of the story. But it really feels incidental, and that doesn't really sit well, especially as it will have significant long-term ramifications within Faerun.
Secondly, the book ends pretty abruptly, and the death of one of the key characters also happens without anyone even seeming to be upset (I don't think it anyone even bothers to mention them after their demise). That struck a slightly false note too.
That said, the basic story is fine, and the writing is good. It is certainly pacy and the ultimate conclusion is satisfying as far as it goes. The action and fight sequences (including a massive scrap between dragons at the end) are certainly fun and exciting. I dunno, it is always tough to end a good series I suppose, but it just seemed a bit careless the way the author just seemed to get bored in the last chapter. Or so it seemed to me.
