Author Harper Lee is to finally going to release the sequel to the critically-acclaimed "To Kill a Mockingbird" after fifty-five years of it being written.

The novel will be named "Go Set a Watchman," and was actually written before "To Kill a Mockingbird," but it was just never published.

"In a statement released this morning, the 88-year-old author explained that when she was just starting off, she wrote "Go Set a Watchman" about a woman nicknamed Scout who returns home to Maycomb to visit her father, Atticus. After reading the manuscript, her editor asked her to rewrite the story from the point of view of Scout as a child. "I was a first-time writer," Lee said, "so I did as I was told." The result was "To Kill a Mockingbird," a novel that has sold 40 million copies since it was first published in 1960," writes Washington Post.

'Go Set a Watchman' was actually forgotten by Lee for many years before being discovered.

"I hadn't realized it had survived," Lee states, "so was surprised and delighted when my dear friend and lawyer Tonja Carter discovered it. After much thought and hesitation I shared it with a handful of people I trust and was pleased to hear that they considered it worthy of publication. I am humbled and amazed that this will now be published after all these years."

Lee plans to publish 2 million copies of the books.

'To Kill a Mockingbird' was such a widely considered success and timely classic, so news of the new book is sure to please fans of multiple generations.

However, there is currently no release date for 'Go Set a Watchman'.
