Robin Hobb - The Tawny Man Trilogy

Vol I: Fool's Errand
For fifteen years, since the events that shattered his old life, FitzChivalry Farseer has lived in a self-imposed exile, assumed to be dead by almost all who once cared about him.
A bastard with royal Farseer blood, he has retreated to an isolated cottage far from the intrigues and dangers of the capital. Now he believes himself content to exist in obscurity, raising his adopted son, Hap, and sharing his solitude with his faithful wolf bondmate, Nighteyes.
Despite the rumors he hears of savage reprisals against those posssessing the Wit magic, he is determined to remain aloof from the conflict. After all he has served his kingdom, sacrificed what was dearest to him, and he deserves his peace.
But all that is about to change when destiny comes seeking him once again. High summer brings visitors to his door, and with them his past. Jinna, a hedge-witch, foresees that a long-lost love will return to him. Chade ? court assassin and Fitz?s mentor from his own assassin days, now growing infirm ? has reasons of his own for desiring Fitz to return to Buckkeep Castle.
And when the Fool, the former White Prophet, reappears as the wealthy and charming Lord Golden, he beckons Fitz to take up his duties as Catalyst, the one who enables others to be heroes and change forever the path of time.
To all of them Fitz says no. He has done his duty ? more than one man should be expected to do. But then comes the summons he cannot ignore.
Prince Dutiful, the young heir to the Farseer throne, has vanished from Buckkeep Castle without a trace. Whether Dutiful has been kidnapped or has fled his impending arranged betrothal is unclear. What is clear is that the Prince is rumored to be Witted at a time when public superstition is running high against those possessing that ?beast magic.?
Endowed with both the royal Skill magic and the despised Wit, FitzChivalry may be the only one who can retrieve the Prince before his betrothal ceremony ? thus sparing the Six Duchies profound political embarrassment … or worse.
But even Fitz does not suspect the web of treachery that awaits him. Everyone seems to have an agenda for the young Prince, and soon FitzChivalry is plunged into a situation where his loyalties to his Queen, his Wit partner Nighteyes, and those who share his magic will be tested to the breaking point.

Vol II: Golden Fool
Prince Dutiful has been rescued from his Piebald kidnappers and the court has resumed its normal rhythms. But for FitzChivalry Farseer, a return to isolation is impossible. Though gutted by the loss of his wolf bondmate, Nighteyes, Fitz must take up residence at Buckkeep and resume his tasks as Chade’s apprentice assassin. Posing as Tom Badgerlock, bodyguard to Lord Golden, FitzChivalry becomes the eyes and ears behind the walls. And with his old mentor failing visibly, Fitz is forced to take on more burdens as he attempts to guide a kingdom straying closer to civil strife each day.
The problems are legion. Prince Dutiful’s betrothal to the Narcheska Elliania of the Out Islands is fraught with tension, and the Narcheska herself appears to be hiding an array of secrets. Then, amid Piebald threats and the increasing persecution of the Witted, FitzChivalry must ensure that no one betrays the Prince’s secret—a secret that could topple the Farseer throne: that he, like Fitz, possesses the dread “beast magic.”
Meanwhile, FitzChivalry must impart to the Prince his limited knowledge of the Skill: the hereditary and addictive magic of the Farseers. In the process, they discover within Buckkeep one who has a wild and powerful talent for it, and whose enmity for Fitz may have disastrous consequences for all.
Only Fitz’s enduring friendship with the Fool brings him any solace. But even that is shattered when unexpected visitors from Bingtown reveal devastating secrets from the Fool’s past. Now, bereft of support and adrift in intrigue, Fitz’s biggest challenge may be simply to survive the inescapable and violent path that fate has laid out for him.

Vol III: Fool's Fate
Assassin, spy, and Skillmaster, FitzChivalry Farseer, now known only as man-at-arms Tom Badgerlock, has become firmly ensconced in the queen’s court at Buckkeep. Only a few are aware of his fabled, tangled past—and the sacrifices he made to survive it. And fewer know of his possession of the Skill magic. With Prince Dutiful, his assassin-mentor Chade, and the simpleminded yet strongly Skilled Thick, FitzChivalry strives to aid the prince on a quest that could ultimately secure peace between the Six Duchies and the Outislands—and win Dutiful the hand of the Narcheska Elliania.
For the Narcheska has set the prince on an unfathomable task: to behead a dragon trapped in ice—the legendary Icefyre, on the island of Aslevjal. Yet not all the clans of the Outislands support the prince’s effort to behead their legendary defender. Are there darker forces at work behind the Narcheska’s imperious demand? As the prince and his coterie set sail, FitzChivalry works behind the scenes, playing nursemaid to the ailing Thick, while striving to strengthen their Skill—ultimately bringing his unacknowledged daughter into the web of the Skill magic, where the truth must finally unfold.
The quest emerges amid riddles that must be unraveled, a clash of cultures, and the ultimate betrayal. For knowing that the Fool has foretold he will die on the island of ice, FitzChivalry has plotted with Chade to leave his dearest friend behind. But fate cannot so easily be defied.
