Margaret Atwood's MaddAddam trilogy of speculative fiction novels spans a landscape of decision trees ranging from community to anomie, and from enlightenment to narcissistic rage. Choices ... which will Homo sapiens sapiens decide to pursue? Set in the later 21st century, a number of Earth's dominant species must contend with global instability in scientific developments, food supplies, climate, and pandemic threats.

Each novel follows many characters as they confront difficult choices, both on their home turf and in faraway realms. Each of these three novels creates a rich experience that yields many startling insights.

Plot Spoiler: With so many variables to juggle across three novels, the discovery of only one inconsistency is an achievement that can inspire many of us to remove our hats in respect. In the second novel, on page 105, it is stated that "Katuro the Wrench used to be an internist." (In North America, an internist is a physician whose specialty is Internal Medicine.) In the third novel, Katuro is one of the novel's surviving characters, at least at that time, yet in the dialogue of two other characters, it is stated, "But before that, I need to do some consulting." "With who? None of our brainiacs are doctors."

As one book reviewer put it, (the novel MaddAddam) is not just "futuristic visions, it's really all about the here and now." Yesssss, and that's why every minute it takes to read all three novels is time well spent. ( )
