Plot summary: The bioengineered living airship Leviathan, after escaping German land ironclads in the mountains, travels to Istanbul (not Constantinople) to deliver a gift to the Ottoman Empire so they'll stop being as mad at Britain for stealing the Erin (formerly Reşadiye) and the Agincourt (formerly Osman I (formerly Rio de Janeiro)) from them. And hopefully prevent the Ottoman Empire from siding with the Central Powers in alternate-universe-World-War-I. It doesn't work.
Our female (but pretending to be a boy so she can be in the sort-of-RAF) protagonist Deryn has developed a bit of a crush on our male protagonest Alek. This is complicated somewhat by the fact that Alek still thinks she's a boy and is like "finally, someone my own age I can hang out with who won't make things weird because I'm a prince!"
Tesla's death ray also makes an appearance. Sort of. Not really. The Germans have "Tesla cannons", which are basically giant reverse lightning rods for shooting down airships with. That's not how Tesla's death ray was purported to work, but it's a neat little detail nonetheless.
Pretty much the entire book takes place in Istanbul, not Constantinople (Istanbul was Constantinople) (now it's Istanbul, not Constantinople) (been a long time gone, Constantinople) (Why did Constantinaple get the works?) (That's nobody's business but the Turks') anyway where was I? Ah yes. As you can see, whenever anyone mentioned either of those names, it set me to singing the They Might Be Giants song.
The titular "Behemoth" refers to a |giant ship-eating sea monster| that goes along with |one of the ships the British confiscated|. To be honest, that seems like |more of a Leviathan| to me, but eh, we already |used that for the title of| the last book.
I actually know quite a bit about the theft/confiscation/what-have-you of the Reşadiye/Erin and Osman I/Agincourt, thanks to my research when I was trying to write a story about them.
4 stars.
Were this a videogame, I'd rate it: T for action scenes.
(Endnote: Given the title, I thought this was going to involve |a giant dinosaur thing|.)
