The world has been waiting for author Harper Lee to write a follow-up to her classic novel To Kill a Mockingbird for more than half a century since the book was published in 1960. And now the wait is finally over.

The book publisher Harper announced Tuesday that it has recently acquired a newfound second novel by Lee. The novel, which is something of a sequel to To Kill a Mockingbird called Go Set a Watchman, was written by Lee in the mid-1950s and will now be published on July 14, 2015.

For so long, Lee, who is now 88 years old, was something of literary legend for writing such a successful debut novel and never publishing another book. It was so surprising that some even speculated that it was Lee's friend Truman Capote who actually wrote the famous debut. However, Lee wasn't the only famous author to have a one-hit wonder. These six literary geniuses only wrote one novel, but the novels were enough to immortalize them forever.

1. Emily Bronte - Wuthering Heights (1847)

With sisters Charlotte and Anne also authors, literature was obviously in the Bronte blood. Emily Bronte began her career as a poet, but she only published one novel, Wuthering Heights, in 1847. Though the novel, which chronicles a volatile love affair over the course of two generations, was not immediately revered by critics, it has become one of the most iconic novels of all time. Unfortunately, Bronte died in December 1848 of tuberculosis before she was able to write another novel.

2, Anna Sewell - Black Beauty (1877)

Anna Sewell became disabled at a young age and was confined to her home for the last years of her life. That's when she wrote Black Beauty, a beloved children's novel about the life of the titular horse and the mistreatment of animals. Sewell passed away just five months after Black Beauty was published in 1878.

3. Margaret Mitchell - Gone with the Wind (1936)

It wasn't long after Margaret Mitchell's novel about Scarlett O'Hara, Rhett Butler and the southern experience of the Civil War and Reconstruction was published that it became one of the best movies of all time upon its release in 1939. Mitchell tragically died after being hit by a car 10 years after the film adaptation of her novel was released, joining the ranks of authors with only one novel. However, in 1995, a novella called Lost Laysen written by Mitchell was discovered and later published as her only follow-up work.

4. Ralph Ellison - Invisible Man (1952)

Ralph Ellison was a prolific writer, penning essays, reviews and short stories in his 80-year life span. However, the only novel in Ellison's repertoire was Invisible Man, which won the National Book Award in 1953. The novel details the life of its young, African-American narrator, from childhood to college to becoming a community leader in New York, and it helped catapult Ellison to worldwide fame.

5. J.D. Salinger - The Catcher in the Rye (1951)

J.D. Salinger had a few short stories published in The New Yorker before garnering instant fame with his first and only novel The Catcher in the Rye in 1951. However, after the success of the novel, which details the adventures and psyche of teen Haulden Caulfield, Salinger famously retreated from public life until his death in 2010 at the age of 91.

6. Sylvia Plath - The Bell Jar (1963)

If you visit a book store — or browse online, let's be real — you're likely to find several book collections of Plath's poems. However, the author only wrote one novel, The Bell Jar, which was published in 1963. The novel chronicles the breakdown of Esther Greenwood, a young woman that seems to have it all. Plath committed suicide just one month after the publication of The Bell Jar.
