From amazon.com:

Yarvi, second son of the feared King Uthrik and the ruthless Queen Laithlin of Gettland, was born with a useless hand, and cannot hold a shield, or make fast a knot, or pull an oar, or do any of the things expected from a man. Left an outcast, he's surrendered his birthright and been given a woman's place as apprentice to Mother Gundring, Gettland's Minister, training to be an adviser, diplomat, healer and translator.

But when his father and brother are murdered by Grom-gil-Gorm, King of neighboring Vansterland, Yarvi is forced to take the Black Chair and become king himself - or half a king, at least - swear an oath of vengeance against the killers of his father, and lead a raid against the Vanstermen. Betrayed, left for dead, and enslaved on a rotting trading galley, Yarvi will need all his Minister's wit and cunning to escape, and all his diplomacy and knowledge to keep a rag-tag band of other slaves together on a month long trek across the frozen wastes of the utmost north. Among them are Sumael, the ship's single-minded navigator, Rulf, an ex-raide, Jaud, an ex-baker, and Nothing, a mad old man with a mysterious past and an almost magical skill with a sword. And their owner, the brutal Captain Shadikshirram, will be dogging their heels at every step. Father Peace may be the patron god of Ministers, but to reclaim the Black Chair, Yarvi will have to strike a deal with Mother War, and once you've invited the mother of crows to be your guest, there can be no telling whose blood will be spilled.
