At the end of Book 1, Michel Strogoff, travelling under the false name of Nicholas Korpanoff, is captured by the Tartars and taken prisoner. However, when Ivan Ogareff, the russian traitor arrives at the prisoners camp, Michel Strogoff is at great risk of being discovered as the courrier of the Czar; designated to travel from Moscou to Irkoutsk in great haste to deliver an important warning to the Czar’s brother, the Grand Duke.
The second book in the two part story tells the tale of Michel Strogoff’s escape and continued efforts to reach Irkoutsk, the Siberian capital, with his travelling companian Nadia Fedorovna, before the traitor Ivan Ogareff arrives there and liberates the city to the tartar army.
This sequel is no less a masterpiece than the first book and I was certainly not disappointed. There are some sad moments but there are some equally happy moments. Un unexpected twist at the end of the book left me thinking for quite a while and I realised just how much of a genius Verne is.
Go out and read this book- preferably in French, but in English if you must.
