This Is Excellent!
The subject matter is a touch on the down side, what with the antagonist being a teenage girl with tuberculosis in a Cape Breton TB sanitorium, whose mother is an unresponsive vegetable after being shot by her father, who then blew his head off.
I'm not sure why I liked this so much, but I couldn't put it down.
Time to catch up on Harry Potter before the final one comes out!
