I just finished Chainfire.
HOLY SHIT!
Best of the series. Seriously. (well, that opinion may be heightened
slightly by the fact that I
just finished it.

)
And don't fret, the series isn't over. It's changed in a number of ways, but to say that this is the last of the series is deceiving. It's true that the SoT series as you know it is over (and from what I can tell, that may only be temporary), but the series you know and love is far from over! That makes no sense right now, I know.
Think of it this way... The Sword of Truth
phase is over, but it's just part of a much longer series, that is continuing. Same series, new phase. We're in Chainfire now. And I can see a number of ways that could take the series closer to SoT and farther from it.
Incoherent ramblings, I know.
Damn, I can relate SO well right now! HAHA! (Again, that only makes sense if you've read the book. and I have. so it makes sense to me.)
I'm actually shaking with excitement. It's so great.
Best series ever.
Terry Goodkind reminds me of Stephen King in a lot of ways. They both tell amazing stories (Terry's much better than King's by a long shot), but they both have a tin ear for the English language. They'll never be noted as great contributors to literature, but by god Terry Goodkind is making one hell of a contribution to story telling as a whole.
