This review goes for the entire series. Any books that can keep my almost-4-year-old so interested and excited that we can discuss them in the car, at breakfast, at lunch, before bed, guess what might happen next, say, "this is kind of like what happened in our book," and that we actually have to have a stack of the next few sitting here "just in case," is a 5 star in my book.

Each one takes Jack and Annie into the pages of a new book. We have learned about (and wanted to investigate further) mummies, space, ghost towns, a player piano, sabertooth tigers, Africa and more. They are a perfect fictional introduction to nearly any subject.

For first read-aloud chapter books, they are really great too because they don't deal with school or interpersonal relationships between friends, teachers, older kids, etc. that a preschooler doesn't have the ability to relate to yet. We have had several other chapter books here, but they were above his head. Not vocabulary (these have great vocab words), but in situation. I also love that these have great adventures that with both a male and female protagonist and situations that both boys and girls could relate to and love.
