I'd heard about this book being an Australian classic, so when I saw the audiobook in the library and read the intriguing premise, I thought I'd check it out. For most of the book I was considering giving it a 3 star rating, although it wasn't amazing, it was holding my interest and I wanted to see how the mystery surrounding the missing girls unfolded. Then I reached the end of the book and thought I'd missed something because I still had no idea what happened to them. I re-listened but it was never explained, leaving me feeling unfulfilled.I have the movie to watch also, so I'll see how that compares. Hopefully that'll shed some light.
