M. Sue Smith and the Dark Wizard (гет)

Miriam Susan Smith’s ordinary, unremarkable life came to an end on October eleventh of the year 2007, at 8:19 p.m., when she was struck by a car while walking home. What happens next could be the afterlife, a vivid dying hallucination, a schizophrenic break--or something else entirely. (It's also her fantasy made reality, so Sue's just going to go with it.)
It's time to save Severus Snape--or die trying.
