Um okay...

So I have read about three really interesting books this summer (harry potter included) and started to read The Milagro Beanfield War and unfortunatly haven't started Song of Solomon, which is what everyone is talking about. I was wondering if we are supposed to read just one or both or only Song of Solomon. Also if we can talk about the other books we have read this summer, like the cheesy ending to harry potter and stuff like that... ?
