The Sagan Diary

The diary structure gives an intimate look into the protagonist's mind, but I wonder if that was planned from the start or a later choice. Did it influence how the story unfolded?

The lines between right and wrong felt blurred at times, making me question the characters' choices. Was this intentional to reflect real military ethics?

The details felt so authentic and immersive. I'm curious whether the author drew from existing science or crafted everything from imagination.
