Might as well just call this book, "And everyone lived happily ever after."
I acknowledge that I may have some sort of sadistic streak in me to want the author to kill off main characters, or at least have something bad happen. Whenever it looked like someone we cared about was going to die, I cheered (thank you for staying dead this time, Ann). The fact that Goodkind broke all the rules he established does not impress me. However, I suppose that was his goal from the start--the theme of the book, and the series itself.
Honestly, overall the series was not as bad as many made it out to be. When I started reading it, I read about the series. Most people focus on Goodkind's use of Objectivism. I agree that it's there, and in some places, it is very annoying. In some books it overwhelms the plot, but most of the books have a good story to them.
As a writer, Goodkind is not my cup of tea. His characters tend to give long speeches. Moreover, as I mentioned above, I am tired of everything working out happily ever after for the good guys. I did not form enough of an attachment to either Ann or Warren to really feel sorry for their deaths. If Kahlan had died, or if her memory hadn't been restored--that would have been respectable. And I'm not just mad because no one died. The ending itself was contrived to grant everyone happiness: Rachel somehow being of royal blood and therefore now the Queen of Tamarang? Adie just happening to fall for Friedlich? It felt a bit anticlimactic--sort of like the ending to Harry Potter (which I didn't actually read; I just read the spoilers and that was good enough).
This last trilogy was very interesting. I enjoyed the Chainfire spell and its integration into the use of the boxes of Orden. Even though it was a bit of a deus ex machina, Richard's use of the Sword of Truth to operate the boxes of Orden made sense.
Judged purely on the merits of its story (and not its themes, which as others say, are heavily entangled with Objectivism), The Sword of Truth series is not bad but could be much better. Many of the characters are very interesting: Richard is a compelling and admirable protagonist. But sometimes the plot seems to nudge them ever so slightly if they get off track; sometimes the story isn't paced right.
The entire series reminds me somewhat of The Wheel of Time, including its length. I could not get past the third book of The Wheel of Time--in the case of this series, I've read all eleven books because my coworker lent them to me sequentially. Had she not done that, I may have consigned The Sword of Truth to the same category in which resides The Wheel of Time.
If you have a summer to spare for these like I did, then give them a try. Do not clear your schedule, however.
