I liked on the the goodreads reviews: “nearly a complete failure by any literary standard.” Indeed. Science fiction often gets a pass if it has a clever or compelling vision of the future, but this was a mash-up of stereotypes, juvenile Foundation-style sociology/psychology, and incoherent plotting. Avoid unless humans develop cell-regeneration technology and you, dear reader of the future, are looking at an infinite lifespan and you are already really bored.
