Captain Nemo's Nautilus in 20,000 Leagues Under the Sea was not the first undersea craft imagined by Jules Verne! A decade earlier, the prophetic author wrote San Carlos, imagining a Spanish smuggler who utilizes a vehicle capable of diving beneath the surface of the waves. This newly-discovered story is published here in English for the first time-together with Verne's final words before his death on the future of the submarine as an instrument of war. Also in this volume is another never-before-translated tale, The Siege of Rome, a historical adventure of love and betrayal as Garibaldi's revolutionaries are defeated in 1849. Sorbonne professor Daniel Compère introduces the expert translation by Edward Baxter in this seventh volume in the Palik series published under the auspices of the North American Jules Verne Society.
