The Castaways of the Flag (French: Seconde patrie, lit. Second Fatherland, 1900) is an adventure novel written by Jules Verne. The two volumes of the novel were initially published in English translation as two separate volumes: Their Island Home and The Castaways of the Flag. Later reprints were published as The Castaways of the Flag.
The story is a sequel to the 1812 book The Swiss Family Robinson by Johann Wyss, picking up where that novel leaves off. (wikipedia.org)
