Ever since Harper Lee's novel, "To Kill a Mockingbird," was published in 1960 and went on to sell 2.5 million copies in its first year and win the Pulitzer Prize, the author has led a low-profile life. Ms. Lee, now 80, has published virtually nothing of significance since then except a 1983 book review. But now she has written something for publication. It is a letter for O, the Oprah Winfrey magazine, about how she became a reader as a child in a rural, Depression-era Alabama town, The Associated Press reported. In the magazine's July "special summer reading issue," Ms. Lee recalls becoming a reader before she entered first grade.
