This is a book which I think appeals to a wide audience. It is a very good read. About a 1/4 of the way through I was worried that it was going to be too predictable. It turns out it is a bit predictable but not too predictable. No real surprises. This doesn't mean it's a bad book. It's a good book and one I would re-read. 
 The story jumps back and forward through time, 1900s London to 2005 Brisbane. It is a bit of a mystery story trying to unravel a family's history. It also has parallels to The Secret Garden which I enjoyed, although the appearance of Ms Burnett herself was not necessary. 
 To sum up... Good book. Recommended.
