The Promise Witch by Celine Kiernan

5.0

After discovering the truth about the Little Grey girl and the horrible past in the castle, Mup and her family try to move into a happier future for everyone - but a curse falls over the land and the water disappears.

Mup discovers she has a limitation to her own magic and learns she must ask for aid, and her good friend Crow has a secret magic power that even he is unaware of but Mup's Grandmother would keenly desire. Crow's mother Magda returns to kidnap Crow and Mup to offer them to the old Queen, but her greed will unleash a greater danger than any Queen's Borough has faced before.

Once again this is a glorious book, not only a joy to read, but the strength and resilience of the characters and the importance of working together, listening, and respecting each other. A gorgeous finale to the trilogy.
