Deen Datta, a Brooklyn rare-book dealer, visits a Sundarbans shrine tied to the legend of the Bonduki Sadagar, a merchant who fled the snake goddess Manasa Devi to a distant 'Gun Island.' With the Venetian historian Cinta, Deen works out that 'Bonduk-dwip' does not mean an island of guns. It comes from the Arabic-Persian 'bunduq,' a name for Venice, which places the merchant's flight in the 17th-century trade world linking Bengal to the Mediterranean.
Folk narratives like the Manasa Devi cycle keep memories of real environmental upheaval, here the droughts, floods, and famines of the 17th-century Little Ice Age, in the form of divine wrath and forced wandering. Reading myth as a compressed historical record lets present climate crises be seen as returns of patterns earlier people already survived and encoded. Dismissing such stories as superstition discards that record.
The novel follows young Bengalis like Tipu and Rafi, pushed out of the Sundarbans by eroding land, cyclones, and lost livelihoods, as they move along smuggler routes to Italy. It frames them as successors to the legendary merchant rather than as a new crisis. Seen this way, today's Mediterranean crossings join the old commercial and ecological circuits that have always moved people between Bengal and Venice, which undercuts the 'unprecedented invasion' framing.
Venomous snakes and spiders turn up far from their ranges, shipworms eat into Venice's foundations, and dolphins and birds gather around a migrant boat. These events are meant to show that a warming world has broken the predictable, secular order that modern realism assumes. The novel stages this through a chain of improbable coincidences.
