As the title suggests, this book is about Nicola and the many things she sees in the Demons' World. There are six short stories, and Nicola visits a city and market, several inns, a tournament, a mushroom forest, and a mansion. Each visit has humorous results, as humans are not allowed in the Demons' World, and Nicola rarely knows the customs and manners of a place. But her new friend Simon is there to help.
Mostly this book is cute. It certainly brings up some alarming topics, but it handles them lightly and focuses mostly on Nicola and Simon's relationship. The artwork is full of harsh lines and thoughtful details, making this a fun little read for a rainy day.
