Magnificently engrossing novel, finest kind . Entirely involving, entertaining and nuanced (that's the new adjective, right?) novel about Hollywood (woo-hoo) during the HUAC witchhunt. Some might call this book a soap-opera but, would that be so bad? Most everything the revered Faulkner wrote is not only soap opera but, gasp, Southern Gothic Soap Opera. LOVED this book which brings back to public consciousness a black period for the U.S. and for democracy and discusses it with a grey palette. Wonderful, exquisite, consuming reading. Well written, with very knowing eye and irony; it's a DO-NOT-MISS-BOOK!
Output:
POS
