The Silver Prince of Slytherin

The Boy Who Lived, was finally going to die. It wasn't a tragic death, mind you. In fact, it was on a warm bed, surrounded by the love of his life, his two best friends, and a dozen or so children and grandchildren. But there were so many regrets and missed opportunities in between. What if he could try all over again? But this time, not as the Golden Boy but a Silver Prince. (AU)
