Query: Science fiction and no attempt to explain science to layman like Hawkins book!

I have read two of his books and am convinced he has no writing skills and his popular science books are just science fiction. There is no attempt to explain hard science principles in layman terms. The books are just chatter and after two chapters I am putting all his books in the "white elephant christmas party" gift wraps of our department!
