Franny's faithful lab assistant, Igor, has swallowed a doomsday device that is ready to go off at any moment! For any regular scientist, there is only one way to get the device out -- um...make that two ways.

But Franny K. Stein is no ordinary scientist, so she concocts her own way to get the device back and save her friend. With her miniaturization machine, Franny shrinks herself to the size of a pin and goes on a field trip like no other...through the body of a ticking time-dog! Fasten your seatbelts, it's going to be a bumpy ride!

            This book is probably about for grades 1st- 3rd. It has a picture on about everypage and the chapters are very short which makes it more fun to read unless you like big chapters. I recommend this to all of the littler kids or even the bigger kids. Totally Recommended!!!
