O.K., the first thing that you have to know about this book is that it was first published in 1912 (in French, 1915 in English). Therefore it’s very ethnocentric and thinks that white people are the bee’s knees and everyone else is less evolved.
The Thorn Birds is an epic, multi-generational story set in Australia’s Outback from 1915 to the ’60’s. If you think, Oh, it is in the 20th Century, life must not have been so bad on an Australian sheep farm in the 1900’s, you are totally wrong.
