Au-delà du monde de Spiderwick : Le chant de la naiade

The whimsical world feels so vivid and unique—I'm curious whether the author drew from folklore, personal experiences, or pure imagination.

The book kept me engaged without feeling too intense, making it great for kids. How did the author find that sweet spot?

The artwork adds so much charm—I'm wondering if the visuals were planned alongside the writing or developed afterward for maximum effect.
