I read the first two books in this series last year and was excited to read the rest of the books right away, well that didn't happen. I had a lot of trouble trying to find a copy of this book, needless to say I did end up finding a copy but out of the entire series it seems to be the only book that is out of print which I found strange considering the copy I found was published in 2006. After finishing the book I'm now starting to wonder if some of the content was controversial enough for the publisher to discontinue distribution in North America, I could be way off on that but who knows. 
 Anyway my only major complaint is the regular use of Aussie vernacular, there's 'An Aussie Glossary' to remedy that in the first few pages but it still bothered me that I would have to look at it every once in a while. Beyond that if you like apocalyptic-dystopian-young-adult novels then you will love this and for that reason I give A Killing Frost four 'fair dinks' out of five.
