Looking for older books by Alice Coldbreath

I've read all the available books by Alice Coldbreath and went looking for some older stuff. I found this list with all (I think) her published books. Here it is

There is a problem - I looked trough all the options of purchase, but none of them showed the older titles (standalones and a novella or two). Has she taken them down? Are the books maybe restricted in some territories (I'm from Europe)?

Could someone suggest a way to buy them or find them if the author has later on published them for free?
