I thought that "Emily Windsnap and the Castle in the Mist" had a good ending, but this didn't take away from it as much as I thought it would, I still don't think this book was a necessary addition to the series. The title didn't work as well as it could have.
Charming finish to this series. Touching at the end with (spoiler alert!) the humans and merpeople learning to get along. Emily gets a boyfriend, keeps her mermaid friend, and makes (or remakes) a human friend. It's a satisfying read.
