This book was a lot of fun.
I've read 4 or 5 of Greenwood's Phryne Fisher series, and enjoyed them as well - Corinna Chapman was a very different sort of main character. Fisher is pretty much perfect - drop dead gorgeous, rich, can do anything, almost like a cartoon heroine - not a problem, fun reading about her, but nowhere near realistic. Chapman, on the other hand, is a much more realistic heroine - heavy build, grouchy in the morning, has to work for a living, not always perfect. And these books are modern day, unlike the Fisher series. So, best not to expect one series to be the same as the other.
I enjoyed the cultural references, the fact that the main characters were intelligent, the quirkiness of many of the characters. Some of the Australian political comments escaped me completely, but they were certainly not essentially to the plot, so no big deal.
