A Parelleled Chance

(This is essentially an AU of an AU called The World Without Me by Eternal Cosmos.) Harry Potter, at age sixteen, enters a duel to the death. He emerges successful but not victorious, for everyone he knew was dead and gone. Fawkes gives Harry the chance to take out Voldemort in a parallel universe where he died. There, he'll see his friends and family, and this time they're alive.
