"In Search of the Castaways" (French: "Les Enfants du capitaine Grant", lit. "The Children of Captain Grant") is a novel by the French writer Jules Verne, published in 1867–1868. The original edition, published by Hetzel, contains a number of illustrations by Édouard Riou. In 1876 it was republished by George Routledge & Sons as a three volume set titled "A Voyage Round The World". The three volumes were subtitled "South America", "Australia", and "New Zealand". (As often with Verne, English translations have appeared under different names; another edition has the overall title "Captain Grant's Children" and has two volumes subtitled "The Mysterious Document" and "Among the Cannibals".)

Jules Gabriel Verne (8 February 1828 – 24 March 1905) was a French novelist, poet, and playwright. Verne was born in the seaport of Nantes, where he was trained to follow in his father's footsteps as a lawyer, but quit the profession early in life to write for magazines and the stage. His collaboration with the publisher Pierre-Jules Hetzel led to the creation of the "Voyages extraordinaires", a widely popular series of scrupulously researched adventure novels including "Journey to the Center of the Earth" (1864), "Twenty Thousand Leagues Under the Sea" (1870), and "Around the World in Eighty Days" (1873).
