This second book I read of the series was just as good as the last. Growing up, my sisters and I were fortunate enough to each have our own bookshelf. Mine had many series of books, each taking up maybe half a shelf. I would love to see this series take up space on my daughter's shelf.

Before finding this series, I had begun to worry that educational mysteries for middle grade readers had gone extinct. This series has revived old feelings of learning from books like the time warp trio and the magic tree house, with the added elation that a girl is one of the main characters.

I have to admit, robotics go a little over my head. But that only added to the book as I was able to learn something new, too.

I love these books! This second novel is just as good as the first in the series. I'm so pleased to see that there are, at least, 3 more to go. My 8 year old loves them, too. What I love best about these books is that they teach science while the kids read. Imagine learning about a "secret spy gadget picker upper" (or some such item), while building an electric magnet from items found around your home. McGyver for kids ; ) Experiments liter the books with easy how to steps, supply lists and diagrams. Can't wait to read more!
