How about "Fields of Gold" by Fiona McIntosh! I've no idea what the book is about but I definitely have a field of gold here!
The Driver and I went to York this morning, a town about 1 1/2 hours east of Perth. There were many paddocks with crops including canola or rapeseed as its called elsewhere. There were also lupins and maybe wheat or barley. It's a bit hard to tell when the crop is low and green ;-)
It rained on and off but the skies were interesting with some lovely clouds. I shall add some more pics in extras
