A space adventure for children around the world, by Dr. Stephen Hawking, a leading physicist of the 20th century, and his daughter. A set of two popular and classic English children's books. - Title 1: George's Cosmic Treasure Hunt - Title 2: George and the Big Bang - Authors: Lucy & Stephen Hawking - Contents: An adventure story exploring the secrets of the universe. - Format: Paperback - Target age: 9-11 years old - Genre: Nonfiction, Adventure, Space, English children's books, Children's literature, Science - Amazon ★4.7 These were my child's favorite books, and they read them often. With illustrations and color photos, and large print, these are easy-to-read foreign books and are staples for extensive English reading, but they are also recommended for adults. Due to being paperbacks, there is some yellowing and staining from aging, and there is a mark from a magic marker on the bottom edge. There are no torn pages or writing, and there should be no problem with reading them. Please check the condition in the photos, and if you like them, please consider purchasing. #Stephen_Hawking #Lucy_Hawking #Dr_Hawking #George #books #foreignbooks #English #paperback #adventure #Englishchildrensbooks #Englishnovels #extensivereading #adventure #childrensliterature #chapterbooks #space #Fiction #Space #Physics #Adventure #astrophysics #secrets_of_the_universe George's Secret Key to the Universe -------------------------------------------------- ※ No comments needed, immediate purchase OK.
