My first fanfic. This is a Sisfic. So don't like, don't read. Sam and Dean's little sister gets sick during a hunt. What the boys don't know is this is not just an ordinary sickness.

While investigating the deaths of employees at an institution for the disturbed, the Winchesters partner with a hunter whose intentions may be less than honorable. With their fifteen year old half-sister MJ along for the ride, drama ensues. Sister fic.
