So I was pleasantly surprised by how much I ended up enjoying it. After a rather grinding start, the story picked up pace for me once the historical back story was introduced -- I would have liked more about the outlaw Kissin' Kate Barlow, and less about the brutality of the camp. Perhaps it's just my tender Australian sensibilities but I was quite shocked by the casual violence and the nonchalant firing of guns -- why are the 'counsellors' even carrying guns, in a juvenile facility in the middle of nowhere? Anyway, the details of the historical story and the events of the present day dovetailed with satisfying neatness, and issues of race, courage and loyalty were handled with a degree of subtlety.
I was planning to jettison this one after reading it, but I think I'll award a place on the permanent bookshelf after all.
