Ordinary World of Prince Aleksander

The book I am reading is Leviathan by Scott Westerfeld. Prince Aleksander of Austria-Hungary's ordinary world is his father's palace. Here is where he is when the story begins and he must leave the palace. He thinks at first he is going to practice driving the stormwalker when they tell him his parents have been assassinated and he must leave Austria-Hungary.
I chose this picture because the Germans and Austrians start chasing Alek and his men when they are fleeing in their stormwalker.
