Versuchung des Zwielichts

The angels in this book aren't just pure beings but have shades of gray. I'm curious what inspired the author to explore this moral ambiguity in angel mythology.

The relationship between the protagonists had moments of passion but also deep emotional conflict. Did it feel genuine and layered to others as well?

The pacing felt well-balanced, but I wonder if the dual timeline was planned from the start or developed during writing to enhance suspense.
