The overarching theme of the book is one of self-discovery and acceptance. Sebastian, as a gay man, feels constrained by the limitations placed upon him by society and his upbringing. His journey to Australia represents a physical and emotional escape from those limitations, allowing him to explore who he truly is and what he wants from life.
Throughout his adventure, Sebastian is confronted with new and challenging experiences that force him to re-examine his assumptions about the world and his place in it. He learns to embrace the beauty and complexity of different cultures, including the Aboriginal spiritual world, and gains a deeper understanding of the nuances of the legal system.
But the murder he witnesses also forces Sebastian to confront his own vulnerabilities and fears. As he fights for his own safety and vindication, he learns to trust in his own strength and resilience. Ultimately, the book is a celebration of the power of self-discovery and the importance of acceptance, both of oneself and of others.
