Assassin’s Apprentice by Robin Hobb

In a faraway land where members of the royal family are named for the virtues they embody, one young boy will become a walking enigma.

Born on the wrong side of the sheets, Fitz, son of Chivalry Farseer, is a royal bastard, cast out into the world, friendless and lonely. Only his magical link with animals – the old art known as the Wit – gives him solace and companionship. But the Wit, if used too often, is a perilous magic, and one abhorred by the nobility.
