Skies of Fire
Louisa and Christopher were lovers and friends. Until Christopher asked a question that out Louisa on the spot. So, instead of talking it out, she took the cowardly way out and left without a word. Fast forward 3 years.
Louisa is a spy. And is pretty fucking good at it too. She also makes bombs. Christopher became what is called a "Man O' War." He received an implant that made him faster, stronger. He is the captain of an airship that gets stuck behind enemy lines.
I liked how they meet again. Even though Louise was in a position that she needed rescuing, it wasn't because she was stupid or a woman. She was intelligent, confident, and able to admit she was cowardly and made a mistake 3 years ago. And Christopher has the confidence to admit when Louisa does something better then him and to be able to forgive.
I would be liked a little more. I thought the end was a little rushed.
