Harper Lee's 'Watchman' book jacket revealed

HarperCollins publishers this morning unveiled the book jacket for the upcoming Harper Lee book, Go Set a Watchman.

Falling yellow leaves. An approaching train.

Barnes & Noble calls it "moody" and "evocative."

What do you think of it?

Here's what HarperCollins' Michael Morrison says in the release:

"There are so many wonderful parts of Go Set a Watchman that it was hard to pick just one iconic image to represent the book. This design is perfect - it draws on the style of the decade the book was written, but with a modern twist."

He adds that "the book begins with Scout's train ride home, but more profoundly, it is about the journey Harper Lee's beloved characters have taken in the subsequent 20 years of their lives."

The book jacket is not unlike the 50th anniversary book jacket for To Kill a Mockingbird, notes B&N.

Go Set a Watchman was the novel Lee first submitted to her publishers before To Kill a Mockingbird. It was unearthed in late 2014.

The story features many of the Mockingbird characters some 20 years later, adjusting to the turbulent events of 1950s America.

The hotly anticipated book — already billed as "an historic literary event" by the publishers — will hit shelves on July 14.
