The Theft of Sunlight

The magic feels so unique and well-developed—I'm curious whether it was mapped out from the start or evolved during writing. How did the author decide on these rules?

The emotional stakes in the romantic relationships really drew me in, but I wondered if that was intentional or just my personal bias. How does the author see the role of romance in the story?

Switching viewpoints added depth but also complexity. I'm curious whether this approach was planned early or developed later to enhance the world-building.
