give me a summary of sdeny in the secret river

"Sdeny" is a term used in the novel "The Secret River" by Kate Grenville. The book tells the story of William Thornhill, an English convict who is sent to Australia in the early 19th century. "Sdeny" refers to the Indigenous Australian concept of denying access or permission to a piece of land, particularly when it comes to the colonizers or convicts attempting to settle on native land. It represents the resistance and protective nature of the Indigenous people towards their ancestral lands and their refusal to let outsiders take control. The concept of "sdeny" plays a central role in the novel as William Thornhill grapples with his desire for land ownership while also recognizing the injustices committed against the Indigenous people.
