George's Secret Key Series

George’s Secret Key to the Universe is a series of 6 books: “George’s Secret Key to the Universe”, “George's Cosmic Treasure Hunt”, “George and the Big Bang”, “George and the Unbreakable Code”, “George and the Blue Moon”, and “George and the Ship of Time” . The stories are about how a boy named George traveled across the galaxy. From just a few of the names, such as “George and the Big Bang” and “George and the Ship of Time”, you can think of what George learns through every cosmic journey. In “George and the Ship of Time”, George learns about how time is slower for you if you traveled at the speed of light. I like this series so much that I even read it two times! The author of this book, Stephen Hawking, is one of my favourite authors. Stephan Hawking is a theoretical physicist. Sadly, he already died. I would recommend you to start reading this book at the age of 8.
