My fifth grader is reading this book for school, so I finally got around to starting it so I could discuss it with him. It's a cute book, discussing how a mouse helps Ben Franklin with some of his inventions, discoveries, and historical acts. 
 The author takes a bit of liberty, so if your children read this alone, discussing it is important. For instance, Jefferson's mouse companion pens what becomes the Declaration of Independence, which Amos gives to Ben, who takes it to the council. But of course it was not Franklin who authored the document. Similarly, the rodent rush on the palace of Versailles bears some similarly to parts of the French revolution, though the women's march on the palace happened several years after Jefferson became ambassador. 
 Overall, however, the story is interesting and enjoyable, a quick and funny read.
