We've struck a deal with our grandson, who doesn't like to read, that if he finishes all seven of the Harry Potter books, we will take him to Harry Potter World in Florida. Of course it's a bribe, but we're determined to turn him into an enthusiastic reader. A Wrinkle in Time, published in 1962, did that for me. Authors Madeleine L'Engle and J.K. Rowling have one important thing in common; they both embrace dark and scary themes, in the belief that children can understand that life is filled with challenges. The cover has changed many times since my parents bought me this first edition, but it remains one of the most enjoyable children's science fiction books of all time. Read it with your children or grandchildren.
