Additional information
by William Lackland (Translator), Jules Verne (Author)
This is the first novel in which Verne perfected the "ingredients" of his later work in the series, skillfully mixing a plot full of adventure and twists that hold the reader's interest with passages of technical, geographic, and historic description. The book gives readers a glimpse of the exploration of Africa, which was still not completely known to Europeans of the time, with explorers traveling all over the continent in search of its secrets.
