Still reading Leviathan!

i am still reading Leviathan, and I'm only about halfway done with the book, and it's the first time I'm kind of happy about this, I really like the book. But when I first started reading the book, there were two main characters, one was named Alek, an Austrian prince, and a girl named Deryn, who ats like a Tomboy and now serves on the Darwinist ship called the Leviathan (there are two sides in the war in Europe, the Darwinists, who have mutant animals as war machines, and Clankers, who use actual machines like tanks to fight the war, a few countries on each side, they each have different views on things) where she serves as a temporary midshipman since she was saved after getting lost while doing her flight test. She's actually pretending to be a man, since women aren't allowed in the military for some reason, and she really wants to be in it.
           Anyway, the book kept on switching between their perspectives, and it was like two shorter books in one, and I wondered why that is. And now I know, it's because Alek and Deryn (or Dylan, her fake boy name) meet up in a weird, coincidental way. Deryn's ship the Leviathan, a big flying whale thing was attacked by German fighter planes, which were mechanical. The Germans attacked them because the Leviathan was a British ship and Britain was an enemy to them , so they attacked. After the long aerial battle, the Leviathan crashed on a mountain in Switzerland, right where Alek and his tutors after escaping Austria to go into hiding after Alek's parent's were Assassinated, so this is how they met. I think it'll get interesting from here because Deryn's British and Alek's Austrian, so they're technically enemies. I know, the book is kind of complicated, but very fast-paced and suspenseful.
