Harper Lee, who hasn't published a new novel in 55 years, has just announced plans to release a novel she wrote in the 1950s titled "Go Set a Watchman."

The novel will be released in July, according to the Associated Press.

Lee wrote "To Kill a Mockingbird," published in 1960, which has sold more than 40 million copies and is one the most-loved books by a Southern author. The Monroeville, Ala., native then went decades without writing another book.
