Terran Tomorrow: Yesterday's Kin #3    by Nancy Kress Order:  USA  Can Tor, 2018 (2018) Hardcover, CD     Reviewed by Hilary Williamson Terran Tomorrow follows If Tomorrow Comes as the third in Nancy Kress's Yesterday's Kin trilogy, starring genetics researcher Dr. Marianne Jenner. In the first book, aliens landed in New York harbor, warning the UN of an approaching spore cloud, carrying death. The Denebs, originally seeded from Earth to a more benign planet, evolved a much more cooperative society. As well as issuing their warning, the Denebs sought humans who were close to them genetically. As a result, Marianne's son Noah and others left with the aliens, when they returned to Kindred. Ten years later, in If Tomorrow Comes, humans launched a ship, Friendship, carrying Marianne and others to Kindred. They were shocked to find that their fellows would age thirty years while they were gone, and also that the Denebs were not the advanced race they had expected. They raced to find a cure to the spore cloud virus, and ultimately flew back to Earth (on another, older ship, the Return). Arriving, as Terran Tomorrow opens, accompanied by several Denebs, they're shocked to find an Earth shattered by biological and nuclear wars, that left only a few million isolated - and warring - survivors. Two of Marianne's grandchildren lead two groups, with very different approaches. Though they have conflicting goals, they do work together in the interest of survival. They fight (the Return providing an advantage) to avoid another deployment of nuclear weapons, and struggle to survive a new illness that leaves many in comas. It also causes profound changes and increased brain activity. Is humanity evolving? Will there be a new Exodus, and and what will happen to those left behind? Marianne believes she has found the answers. Though the series moves slowly at times, this conclusion was filled with action and conflict. This trilogy is well worth reading.
