Our Book Club reconvenes to discuss John Scalzi’s novel “The Human Division,” which was initially released as a serial and later as a single-volume novel. Does the serialized format help or hurt? Is Scalzi’s return to his “Old Man’s War” universe a triumph? PLUS! We discuss all the short fiction nominated for the Hugo Award this year.
