Here is a link from Nate's Digital Reader (now known as Ink, Bits & Pixels). I don't usually post these, but this is incredible news. To Kill a Mockingbird is undoubtedly one of the greats, and I have often been saddened by the fact that Harper Lee had published nothing else. But the circumstances surrounding this new publication raise issues of their own (please see the comments in the link) coming so soon after the death of Lee's sister, lawyer and protector who she compares to Atticus in the book (describing herself as Boo).
