The gun club of "From the Earth to the Moon" and "Around the Moon" returns after a long retirement. "The Purchase of the North Pole" brings back the three explorers who have come up with a new engineering project. If they fire a huge enough cannon, they can achieve displacement of the Earth’s rotation axis. They seem to have a secret motive and we are left to wonder what they expect to achieve. Why are they not willing to give up on their plan? Have they made a huge mistake? Let's hope it's not too late to save the world from the damage one gun club can cause.Jules Verne (1828-1905) was a French novelist who mostly wrote adventure fiction inspired by the scientific advances of the 19th century. With the help of editor Pierre-Jules Hetzel he wrote a series of books called "Extraordinary Travels", which includes "Journey to the Center of the Earth" (1864), "Twenty Thousand Leagues Under the Sea" (1870), and "Around the World in Eighty Days" (1873). There have been many film adaptations of Jules Verne’s books with the most notable being "Journey to the Center of The Earth" (2008) starring Brendan Fraser and Josh Hutcherson (The Hunger Games), "Around the World in 80 Days" (1956), and "Journey 2: The Mysterious Island" (2012) starring Dwayne Johnson. Widely popular with both children and adults, Verne is one of the most translated authors of all time, and still inspires people the world over.
