Lundi mystérieux

The world-building in Mister Monday is so imaginative — I wonder what sparked the idea for this secret universe and its rules.

It’s a lot for a kid to handle, but it also makes sense in the story’s universe. How did others feel about Arthur stepping into such a huge role so quickly?

The book balances lighthearted moments with darker stakes, and I’m curious whether the tone was planned to keep young readers engaged without overwhelming them.
