I am just getting started reading Ian Wishart's new book now, but I have to say it appears to be selling very well. It took me ages to find any place that had a copy. First stop was Borders in Sylvia Park who had sold out. Next I tried both Whitcoulls and Paper Plus from my local Westfield Mall and it had sold out both places there as well. Eventually I found a Whitcoulls that had a copy, although it took some hunting around to find it (they also told me it had been selling very well).
Looks like it's going to do as well as Eve's Bite, or maybe even better!
