Artos 'The Demon Wolf'

When Lyanna Stark is taken and Rickard and Brandon burn, the North rises. But not only under Ned Stark’s banners. At just fifteen, Artos Stark—forged in battle, driven by wolf-blood—rallies greybeards, Umbers, mountain clans, and even the Skagosi out of isolation. Leading from the front, he wins impossible battles: outnumbered by the Reach, defying the Crown’s hosts, carving legends in steel and blood.Gifted—or cursed—with the warg’s sight, astride his white stallion Snow and an eagle called Rick, Artos becomes more beast than man in war. Enemies scream of the "Demonwolf," a Stark born of fury, who makes kings and knights alike tremble.But rage is a double-edged blade. As rebellion burns across Westeros, Artos must decide whether he is a commander of men…or a monster of the Old Gods. — Description from novelcodex.org
