The year is 1845. Since Napoleon’s famous victory at Waterloo, France and Britain have been locked in a long and bloody war for global supremacy. This breathtaking steampunk adventure introduces an alternative 19th century of giant airships soaring through the skies above the English Channel, fantastical, steam-powered automata, aerial steam carriages, floating cities, giant mechanical birds and a new kind of secret agent. Enter the world of Iron Sky… In this version of reality, an ageing Napoleon is threatening a full-scale invasion of Britain. Opposing him is Sir George Jarrett, head of the Imperial British Secret Service, helped by an all-female team of aerial spies known as the Sky Sisters. The youngest of them is Lady Arabella West. As war clouds loom, airships start to disappear, and rumours spread of a mysterious terror in the skies. Arabella, with the help of her automaton sidekick, Miles, sets out to investigate.
