I read the synopsis of this one and was wary to even read it, but I'm glad I gave it a chance.
Acid Walls
by Spike'sSavior
Chase, House, & Wilson wind up investigating a school that was burned many years prior. Chase can see dead people. And Demons. And it's actually really, really cool because it's so different from anything else I've read in House fiction. Just give it a chance before dismissing it.
