What is the title of J.K. Rowling's 2021 children's novel about Jack's missing toy pig?

The Christmas Pig is J.K. Rowling's 2021 children's novel about Jack's missing toy pig.

The story follows Jack, whose beloved toy Dur Pig is lost on Christmas Eve. A replacement toy, the Christmas Pig, helps him enter a magical realm where lost things can be found. The adventure gives the book a seasonal setting while focusing on grief, attachment, friendship, and the emotional importance of familiar objects.

The novel was Rowling's first children's book published after the Harry Potter series and The Ickabog. It is a standalone story rather than a continuation of Harry's adventures. Its fantasy world is built around the idea that lost possessions have their own places and meanings.

The Christmas Pig was published in 2021 with illustrations by Jim Field. The title can cause confusion with holiday picture books or films using similar wording, but Rowling's novel specifically centers on Jack, Dur Pig, and the magical replacement toy.
