We started Nanberry this week as our current Aussie Read Aloud. We most likely won't finish this book before term break, but that hasn't stopped us from enjoying it. It's all ready covered a few things that our other books have only barely graced over which has fully delighted me.
If you're looking for a little extra with the book, discussion questions, time frames, research ideas, websites, or even notes from the author there's a lovely PDF put together by Book Vibes. There's a lot of information in there, probably more then you'd need or even want to use, but it makes an interesting read & you never know you might find some really lovely jumping off points for discussion while reading the book.
The book itself is well dated, in regards to keeping a timeline of actual events if one wanted, as well as giving specific places to keep track of on a map. However, you might want to preview the book before reading aloud as it is an emotional story. You'd have to decide for yourself if it's right for your family.
