崖の国物語〈3〉神聖都市の夜明け (ポプラ・ウイング・ブックス)

The world feels so vivid and imaginative—I'm curious what inspired the unique setting and its rules. Was it based on any real-world ideas or entirely from imagination?

The tension around Midnight’s journey made me wonder if this was the most suspenseful part of the series so far. How did the author decide where to ramp up the danger?

It’s rare to see a middle-grade fantasy that feels both playful and intense. I’d love to know how the author approached blending these moods.
