I think I've mentioned it many times on these forums. Tawny Man is better than Farseer, but Assassin's Apprentice is the best book of the lot.
I thought the whole Fitz series was great. I don't understand why so many people piss on about the ending, there was nothing to be pissy about.
For me it's not Fitz's happy ending that irks me about the end (yes, he finally redeemed himself in my view in Tawny Man) but other characters I didn't like
eg. Elliana (what does Dutiful see in her, apart from boobs??) and Thick (gosh he is hands down one of the most annoying characters I've ever read about...).
