In the second volume of the Leviathan trilogy, Westerfeld takes the crew to Istanbul (not Constantinople!). The unusual setting, daring midnight escapes, adventure and intrigue will keep readers turning pages late into the night. Some tantalizing secrets are revealed, like what’s been growing inside the eggs the lady boffin tends to so carefully, while others, like Deryn’s true identity, are safe for now — at least from some people.

Now that the Darwinists and Clankers are at war, both sides seek the support of the Ottoman Empire. Alek and Deryn end up on their own in Istanbul, forced to make new allies, navigate unexpected dangers and do what they can to stop the war.
