These books can be bought around the globe! If you live in Australia the easiest way to get them is from Living Book Press.
They are print on demand paperbacks. We're trying one book, Buzztail and Leaper, in hardcover to see how people like it. If all goes well then we'll offer more in hardcover like Coal Camp Girl.
For the US we're releasing many of these titles on our site May 21st, for major retailers the release date is May 24th. Before then we'll add affiliate links on their pages here to help you find them in other countries, and if you decide to use the links it'll also to give us an extra boost of support.
On each page is the release date or an estimate. Have fun browsing!
