Everything you need to understand or teach Gun Island by Amitav Ghosh.
Set between modern-day India, America, and Italy, Ghosh's novel follows one man's journey of self-discovery while walking in the footsteps of a legendary figure. Told through the eyes of a defeated and lonely American immigrant in his late 50's, Gun Island tackles issues of displacement, spirituality, and ancient tradition converging with modern society. The novel calls into question morality and environmental issues as key characters face personal and professional challenges while escaping with a deeper appreciation for the world that surrounds them and the legends that created them.
