Assassin's Quest is the last book in the Farseer trilogy, first published in 1997. Previous books in the series are Assassin's Apprentice and Royal Assassin. The next book that concerns Fitz directly is Fool's Errand, but chronologically what follows the Farseer trilogy is the Liveship Traders trilogy, and it is highly recommended to read those first.
