La primera llave (Serie Ulysses Moore 6)

The key feels like such a classic symbol of unlocking secrets and new worlds. I wonder if the author had a specific inspiration for this motif or if it evolved during writing.

The pacing kept me engaged without feeling rushed, and the humor made the characters really come alive. How did the author find that sweet spot between excitement and fun?

The magic system felt consistent and well-thought-out, which added depth to the story. I'm curious whether it was planned from the start or developed as the story progressed.
