Fool's Fate by Robin Hobb

"Complex . . . an atmosphere-filled adventure . . . with a fair quota of surprises . . . a winning combination of strong characters and colorful societies."—Kirkus Reviews
In the final book in the Tawny Man Trilogy, Fitz and the Fool are tested more severely than ever in a book the Monroe News-Star calls "a breathtaking ride from beginning to end."
FitzChivalry Farseer has become firmly ensconced in the queen's court. Along with his mentor, Chade, and the simpleminded yet strongly skilled Thick, Fitz strives to aid Prince Dutiful on a quest that could secure peace with the Out Islands—and win Dutiful the hand of the Narcheska Elliania.
The Narcheska has set the prince an unfathomable task: to behead a dragon trapped in ice on the isle of Aslevjal. Yet not all the clans of the Out Islands support their effort. Are there darker forces at work behind Elliania's demand? Knowing that the Fool has foretold he will die on the island of ice, Fitz plots to leave his dearest friend behind. But fate cannot so easily be defied.
