When the blessed became the cursed

When a young boy named Castiel Novak ends up in a hospital without his "guardian angel" by his side, how does he try to fix his life. When he finds two boys watching him through his window at night, he enters a race of life or death and his "guardian angel" just happens to be the one controlling it all.

This is a Supernatural Au so dont hate. All characters except for a few ocs belong to their rightful owners.
