So many sci-fi books come across as basically the same, I like
Forge of God precisely because it is so dark and uncompromising and is like works like
Gateway and
Worlds or Ballard’s works that read more as literature than genre sci-fi.
Also from the view point of SETI there is the awful truth that we really shouldn’t be trying to communicate w/ other life because the most practical meaningful form of interstellar communication is bombing with relativistic or sub-relativistic projectiles. See The Killing Star where aliens watched Star Trek: The Original Series and thought we might be dangerous, then saw Star Trek: The Next Generation and realized they could take us.
