The Pendragon Way, by
dreamdustmama ; NC-17 ; Two Parts ; 14k words
A/S: Arthur answers an ad in the paper for a third flat mate, and his life is turned completely upside down. It's the best decision he's ever made.
This fic is absolutely fabulous. Even better than what the summary lets on. It's Arthur, 25, deciding to finally take his life in his own hands as opposed to his father's. He discovers a lot of wonderful things along the way, and the good parts overcome the bad ones by a lot!! It's a story about flying by one's own, and hope and love, and it's delightful...
