"Aurora" is the Sword & Laser book for May 2016. This is my first Kim Stanley Robinson novel and it focuses on the impact of interstellar space travel at sub-speed-of-light (10% of c), no 'hibernation' and several 'biomes' with a variety of life and agriculture to sustain life during the trip and to begin life on a new planet.
How does a ship with last for hundreds of years barrelling through space and what about the evolution and genetics over the generations of humans and animals and plants? These are the questions explored with our narrator, an AI, struggling with the concepts of consciousness and self-consciousness.
Some good points were made but the story fell flat several times.
