Reading progress update: I've read 198 out of 319 pages.
I'm really liking the second novel. So far Silverberg's story is focused on the development of an ad campaign by the protagonist's agency designed to justify the subjugation of the Ganymedeans, involving their dehumanization and the creation of fictional atrocities. This alone makes the book interesting reading, but in spite of its 2044 setting there's also a enjoyable Mad Men vibe to the setting, which makes sense for a book published in 1957.
