Reef is a historical fiction novel written by Sri Lankan-born British author Romesh Gunesekera, first published by Granta Books in 1994. Written in English and set in Sri Lanka, it tells the story of a talented young chef named Triton who is so committed to pleasing his master, Mr. Salgado, a marine biologist obsessed with swamps and seafood, that he is oblivious to the political unrest threatening his country. It is Gunesekera's debut novel and second book, following his 1992 collection of short stories, Monkfish Moon.
