everything you want to be (джен)

While trying to duck out of the semi-hostile crowds of Hogwarts in the aftermath of three months of Daily Prophet's manipulation of the general public, Harry finds himself somewhere decidedly not at Hogwarts, but also probably still in Great Britain.
He doesn't start to panic until he realises that his little transportation problem is not only spatial, but also temporal.
Stuck fifteen years into the future, to keep any hope of going back home, Harry is forced to face the man destiny wants him to become. The same man the older versions of his best friends are claiming is the best version of himself, the man who for some unknown reason looks more like a corpse than a human being.
