Game of Thrones: The Wolf of Deepwood Motte

An unexpected twist of fate sends Garlon back in time into the world of Westeros, where he becomes the only son of Galbart Glover, heir to Deepwood Motte in the North. Knowing the disasters that will soon engulf the Seven Kingdoms, Garlon refuses to stand by and watch history repeat itself. Before Eddard Stark departs for King's Landing, Garlon makes a daring choice that shocks the North: he seeks the hand of Sansa Stark, placing himself against princes, great houses, and the deadly game for the Iron Throne. Years later, as Garlon Glover sits upon the Iron Throne, he still remembers the night he crossed swords with Joffrey Baratheon for Sansa's hand. The night the fate of Westeros began to change. — Description from novelcodex.org
