Jack and Annie are new Master Librarians for Morgan Le Fey, and they are tasked with the retrieval of four lost stories. This particular episode sends the kids back in time to medieval Ireland, where they must retrieve an illuminated manuscript from a group of monks before vikings arrive and pillage the place.
This had some fun plot twists, including a deus-ex-machina that was so over-the-top that it still falls into the "fun plot twist" category.
The Kiddo enjoyed some of the little touches in this when we read it out loud. We've gotten into the habit of correcting Jack's "Oh, brother!" catchphrase that he uses every time Annie proposes a particularly rash course of action to the more accurate, "Oh, sister!". Kiddo also laughed out loud when Jack, in a particularly harried moment, says the wish to get them home very loud and fast. Repeated phrases and little variations are a big part of what makes this series work for a six-year-old, and Osborne works them masterfully.
She also did a nice job of working an Irish blessing into the story, as well as some good discussion of the concept of civilization, which the kids end up defining as reading and writing books and playing chess in a warm and comfortable room.
I could get on board with that definition.
