Perhaps Harper Lee should have had her sister Alice review the contract for her before signing? As of this time last year Alice Lee was still a practicing attorney.
Seriously though I hate to see an older person like Harper Lee take advantage of. I hope she will prevail in her lawsuit.
I am also always puzzled by those who think that they have a right to any book in ebook format, even if against the wishes of the author. I prefer ebooks, but do not think I have the right to demand that the author approve release of their book in that format. Especially with all the pirating going on.
