Author Harper Lee, whose first and only novel To Kill a Mockingbird became a literature classic, will publish a sequel this summer.

HarperCollins announced Tuesday that Go Set a Watchman, described as “essentially a sequel” to the author’s first book, will hit store shelves in July.

“In the mid-1950s, I completed a novel called `Go Set a Watchman,'” said Lee in a statement. “It features the character known as Scout as an adult woman, and I thought it a pretty decent effort. My editor, who was taken by the flashbacks to Scout’s childhood, persuaded me to write a novel (what became `To Kill a Mockingbird’) from the point of view of the young Scout.

“I was a first-time writer, so I did as I was told. I hadn’t realized it (the original book) had survived, 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.”

Carter discovered the manuscript to Go Set a Watchman attached to the original typescript of To Kill a Mockingbird.

Go Set a Watchman is 304 pages and will receive no revisions. It was reportedly written before Mockingbird, which was published in 1960. Despite Lee’s resistance to eBooks, the novel will be published digitally (just as To Kill a Mockingbird was last year).

According to the publisher’s synopsis, “Scout (Jean Louise Finch) has returned to Maycomb from New York to visit her father, Atticus. She is forced to grapple with issues both personal and political as she tries to understand her father’s attitude toward society, and her own feelings about the place where she was born and spent her childhood.”

Lee, now 88 years old, is unlikely to do any publicity, according to the Associated Press. So don’t expect any Twitter Q&As or road tours.
