The Winchesters have been subjected to a lot of things in the name of hunting, but the result of a spell-gone-wrong on their latest case is still pretty high on Dean's weird scale. While their father is out searching for a way to undo the magic, Dean's stuck in a cabin in the middle of nowhere, trying to deal with his bitchy teenage brother and his own increasingly un-brotherly feelings toward him.

Sam and Dean have always been oddities among the dragonriders; the youngest man to Impress a Bronze dragon in a hundred years and a boy who turned his back on the riders to become a dragon healer instead. But when fate steps in and chooses a far different path for Sam, the brothers and all the Weyrs of Pern will have to come to terms with much greater changes in their traditions.
