In Kelley Armstrong's latest YA trilogy she mentioned the residential schools since her MC is Native American (the character was originally from the States) and living on Vancouver Island for the past decade. No description but I gathered from the tone of the sentence that they were disgusting.

Once I get a minute again, I'm going to look them up. Because I have a feeling it's going to be relevant to the series and as I like Maya, I should know these things. Also because sometimes tells me as a non-Canadian this should be read about if it comes up again since Armstrong uses Canada (various parts) occasionally.
