Where could I get more books by Дарья Донцова / Darya Dontsova / Darja Doncova (detective fiction)?

I have read one book by this author and I liked it very much--so much that I definitely want more. However, it was the only one translated into Czech and sold there. Unfortunately, I DON'T understand Russian, but I think I could give it a try in English or German if possible. Does anyone know about such translation available in their country?
