sequel of "to kill a mockingbird"

On this coming Tuesday, a sequel to the magnum opus, "to kill a mockingbird", will be published. I still remembered vividly, even after 50 years, the touching scene when the upright lawyer, Atticus Finch (played by Gregory Peck), despondently walked out of courtroom while all black people on the gallery stood up to show their respect. Now, this sequel totally upends this indelible image since Atticus Finch was a racist as revealed in this sequel. Though this is a fiction, "to kill a mockingbird" is a book that all U.S. school children have been required to read in the last 50 years, its impact will be enormous, especially in this era of racial conflicts.
