    Lucky for us, award-winning book illustrator and political cartoonist David Catrow has taken the most important introduction in our country's history and made it easy to understand in a hilarious, inspiring new book.We the Kids follows three adorable youngsters and one remarkable dog as they get ready for a camping adventure in the great outdoors. What makes this adventure different is that it is told through the Preamble. Just as the historical document starts out with "We the People of the United States," we're introduced to the children and their energetic pooch friend, who is standing by with a gargantuan, overloaded backpack. As the Preamble goes on, then, so does the story: They find themselves forming a More Perfect Union by finding their camping site, promoting the General Welfare by telling stories around a campfire, and securing the blessings of Liberty by settling down for a good night's sleep -- all in the backyard under the watchful eyes of two parents. With bright watercolor illustrations and sweet, cartoonlike characters, Catrow provides an entertaining story that brings the Preamble to life. The dog's actions throughout the book are truly sidesplitting, but they also explain to young readers each line of the Preamble. A fun introduction from Catrow called "Big Words, Big Ideas.&quot and a line-by-line explanation of the Preamble add to the book's pleasures.For school reports and American holiday celebrations, this is one book young historians won't want to miss.

      Louis Braille was just five years old when he lost his sight. He was a clever boy, determined to live like everyone else, and what he wanted more than anything was to be able to read.   Even at the school for the blind in Paris, there were no books for him.   And so he invented his own alphabet—a whole new system for writing that could be read by touch.
