The High King by Lloyd Alexander
When the most powerful weapon in the land of Prydain falls into the
hands of Arawn, Lord of the Land of Death, Taran and Prince Gwydion
rally an army to stand up to the dark forces.
The companions' last and greatest quest is also their most perilous. The
biting cold of winter is upon them, adding to the danger they already
face. Their journey, fraught with battle and bloodshed, ends at the very
portal of Arawn's stronghold. There, Taran is faced with the most
crucial decision of his life.
In this breathtaking Newbery Medal-winning conclusion to The Chronicles
of Prydain, the faithful friends face the ultimate war between good and
evil.
