Verne wrote two trilogies; the first includes The Children of Captain Grant, Twenty Thousand Leagues under the Sea, and Mysterious Island; the second comprises From the Earth to the Moon, Around the Moon, and Topsy-Turvy (also known as The Purchase of the North Pole). Journey Through the Impossible is the only piece where so many characters from other works-including both trilogies-appear together. The first half of Jules Verne's life and work culminates with journey Through the Impossible, a mantle atop the two trilogies.
