Another hilarious episode in the life of Nathan and Delphine.

Nate Bannister and his friend Delphine are, once again, put in a position where his gadgets have to save their city. Fast paced, funny, and entertaining, it is a must for middle-school classroom libraries.

The science connections and adventure in this book are amazing! For middle grade readers I find this book intoxicating! I would highly recommend for any females who feel drawn towards science fiction, adventure, *cough*boys*cough*; and for the boys who love anything science, robot, world saving hero, gifted/talented student. I love that the girl protagonist is one who students can relate to and/or strive to be like. This book is humorous, adventurous, and leaves a great cliffhanger! I would recommend grades 3-6!
