Hi Randi, if you click on the NZ Book Council link above, halfway down the page you'll find an interview with Yvonne where she answers some of the students questions.

"Writers in schools information
Du Fresne is available to visit schoolchildren of any age as part of our Writers in Schools programme. She is happy to discuss writing about her Danish roots in New Zealand, and using her local landscape in Makara and Karori in her writing."

I have just finished rereading her 'Motherland' novel and I recognise so much of Astrid's thoughts and memories. Yvonne was Astrid.
