I enjoyed rereading this after a decade or so, but I found I had some issues with it that I did not have before. Maybe my tastes have changed; if so, that would be quite fitting with a novel like this one! Like the other two previous volumes in the Destiny's Children series, Transcendent has two different, albeit ultimately interacting, timelines. The first is a dystopian near future (2047) where global warning and the drying up of oil have produced major changes in societies across the globe. Our lead, Michael Poole, is the nephew of Michael Poole from the first volume in the series. Transcendent assumes the form of Michael's reflections on his life and his meeting with a being from the far future (Alia) sent back to his timeline. Michael is an engineer, who worked on Nuke power plants and also taught at Cornell, but is currently between jobs so to speak. His son works on a project in Siberia trying to gather DNA of various species before they become extinct. His older brother lives in the US, and works as a kinda environmental lawyer. His mother, aged in the 90s, serves as a fulcrum in the story. Michael's brother asks him to come to Miami to help with her (he thinks she is losing it) and pays for his flight. Once there, however, he learns of a terrible explosion in Siberia and his son Tom is hurt...
In the far future, Alia, a woman born and raised on an ancient generation ship/habitat is being courted to become a member of the Transcendence-- a melding of the minds of humanity that will achieve godlike status. Part of her earliest training entailed 'witnessing' Michael Poole's life-- something the Transcendence made possible, e.g., this perfect rendering of Michael's existence from birth to death. The Transcendence, while in a process of becoming, is vexed by the concept of redemption for all the suffering and death of so many humans that came before. The hope of 'witnessing' is that the past will not be forgotten, but more, that the future can atone for the sins of the past.
While I loved the world building of Michael's timeline-- the abandonment of private cars, the harsh global warning fundamentally changing the world and the construction of new social institutions, the entire transcendence idea struck me this time reading it as rather problematic, laced with too many religious overtones to really be taken seriously. Why would some future group intelligence really care about past human suffering, let alone feel that they must seek redemption? If you can get over that, Transcendence is a very good read.
The character building of Michael and Alia flows well, and perhaps strangely for a hard science fiction novel, science does not serve as a 'character' if you will. Sure, we have some great discussions of new tech to help stabilize the planet's ecosystem, but nothing to avant garde, and it only comes into help build the narrative. Baxter, as he is prone to do, probes some serious philosophical questions, not just about the human condition, but about what gives life meaning, the nature of death and life, and so forth that was refreshing. 3.5 stars rounding up.
