After finishing Assassin's Quest, I was left wondering how after two good books this could was given to readers to finish up the Farseer Trilogy. Following Fitz's journey to regain his humanity then seeking vengeance against Regal and then journeying to find Verity has all the prospects of an exciting book, however the result was tedious details that were repeated every couple of pages and then were the info dumps that actually had to be rushed(!) before the climax of the book. And then after all the build up of the Red Ship War that the reader has been experiencing along with Fitz over two books, the end of the war isn't experienced it's described afterward to the reader's frustration.
There were plenty of bright spots throughout the book, even when some of them were tainted with the book's overall flaws. The magic of the Wit and Skill were better understood, the mystery of the Fool and his interest in Fitz, Chade's reemergence into public knowledge, and the unique type of dragons created in this fantasy. Fitz's interactions with a host of characters from familiar to new acquaintances was a mixed bag in terms of his character development, especially when it came to Kettle who Fitz should have verbally rounded on earlier than he eventually did.
Assassin's Quest is essentially a mixed bag. The book doesn't reach the level of bad, but it is disappointing as the finale of the Farseer Trilogy. If you've read the first two books then you should read Quest, but don't expect a fantastic finish.
