From my Deathbed

Harry Potter, The boy who lived, is now the boy on his deathbed.
Harry wakes up in the hospital in August before his third year. He has no memory of how he got there. And what's stranger; the Dursleys are being nice to him?
Harry learns that he has Leukemia. The doctors estimate he'll have until June to live. It's deemed that he will likely never see fourteen.
But the staff and students of Hogwarts refuse to accept that. They are determined that Harry will live. They will give him every treatment, Muggle and magic, to make him better.
But will it be enough?
