Now the heroine, Nikki, is back in the Land of Reason with a new adventure called, “The Prince of Physics.” These are fun stories and offer an imaginative review of subjects your kids already probably know. Also you can read them to a wide range of ages at once. For the little ones the story is a first introduction to a lot of ideas and concepts and for the oldest it is a fun story with a review of past lessons. All in all, a great activity for summer!
