The cover of Harper Lee's much anticipated sequel to her classic book To Kill a Mockingbird has been revealed.

Penguin said that the book, which will be called Go Set a Watchman, will be set during the mid 1950s and will feature many of the characters from To Kill a Mockingbird, including Scout (Jean Louise Finch).

In the book Scout has returned to Maycomb from New York to visit her father Atticus and is forced to grapple with issues both personal and political as she tries to understand both her father's attitude toward society, and her own feelings about the place where she was born and spent her childhood.

Harper Lee has been awarded numerous literary awards for To Kill a Mockingbird, including the Pulitzer Prize and the Presidential Medal of Freedom.
