Query: I wish I COULD review this book

Dear amazon. I LOVE reading books on my kindle. In fact, if you check my account you'll see that I can average a book a day. So when I start working my wa through a list of books I get really, really frustrated when suddenly, unaccountably, they become unavailable to readers from Australia. Now I know that clutch of constables and the ngaio mars books that follow it are available in kindle format from amazon uk...so I wonder why not from amazon.com?? And why not to readers from Australia? Please, please make the rest of the list available to us. I just don't read real books anymore just my iPad ones!
