Gun Island : a novel / Amitav Ghosh.

A dealer of rare books, Deen is used to a quiet life spent indoors, but as his once-solid beliefs begin to shift, he is forced to set out on an extraordinary journey; one that takes him from India to Los Angeles and Venice via a tangled route through the memories and experiences of those he meets along the way. There is Piya, a fellow Bengali-American who sets his journey in motion; Tipu, an entrepreneurial young man who opens Deen's eyes to the realities of growing up in today's world; Rafi, with his desperate attempt to help someone in need; and Cinta, an old friend who provides the missing link in the story they are all a part of. It is a journey which will upend everything he thought he knew about himself, about the Bengali legends of his childhood and about the world around him.
