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!

If you are looking for a story that combines adventure and science then this series is definitely what you are looking for. The kids and I enjoy reading this and trying to create science experiments together. It makes for a fun and educational library program.

Having read the first book in the Nick and Tesla series I had high hopes for Nick and Tesla's Robot Army Rampage. Needless to say, I was not disappointed. Nick and Tesla have stumbled upon another plot to solve through using cunning and new inventions! Everything that I said in my previous review is true of this book- it is well written, highly entertaining, and in all honesty- it is also inspirational in a way. Though this crazy summer Nick and Tesla are experiencing is not typical, it provides an escape for readers while also showing kids that it is possible to make a difference, help friends in need, and accomplish that which may seem impossible by never giving up. I was so impressed when the twins were confronted with an unexpected problem near the conclusion of the book where instead of reverting to desperation or losing the will to continue in their efforts- their immediate thought is 'what can we do now to combat this new challenge and what materials do we have at our disposal to accomplish it'. And in a world where most people (and an increasing number of youth thanks to the entitlement generation) want to give up when there aren't clear cut, easy solutions; the Holt twins continue to surprise me by being great role models who never give up even when faced with uncertainty and difficulties. I can't wait to see what other adventures await them this crazy summer!
