Antsy’s story began in Lost in the Moment and Found, and this book is a lovely conclusion for her.
The last book ended with Antsy leaving the Shop Where all Lost Things Go, angry at the price that children weren’t being warned they’d need to pay if they opened doors from the shop. In the end, she found her way to Eleanor West’s school. But she’s not happy there – she doesn’t feel like she really fits in.
In this new story, some of the other children at the school figure out that Antsy still has the ability to find any Door, and there are two very different reactions to that. She finds her friends in the group that doesn’t want to use her power to get them back to the worlds they were expelled from, but they end up having to use her power to escape through a Door from the other group.
So we end up with some endings – in some cases, verifying that old friends are safe in the worlds they wished to be in, and in other cases, verifying that even though Antsy could get them were they want to go, they want to wait until they’re ready. And Antsy herself finds her way back to the Shop, and there’s a very satisfying ending to her part of the story.
