The AP reports that Harper Lee will publish her second novel this summer, a sequel to the Pulitzer Prize-winning classic "To Kill a Mockingbird."

The book, entitled "Go Set a Watchman" was completed in the 1950s, but an editor convinced Lee to focus on one character in particular, a woman called Scout. The second effort, focused on Scout's childhood, would become "To Kill a Mockingbird." The original manuscript was discovered by Lee's friend and lawyer, Tonja Carter.

"The existence of 'Go Set a Watchman' was unknown until recently, and its discovery is an extraordinary gift," Harper publisher Jonathan Burnham said in a statement.

Lee’s original novel examined the roles of race, class and gender in 20th century America, and has sold over 40 million copies worldwide since its debut in 1960.
