by Stephen Baxter (2009). Continues where the hard science fiction novel Flood left off. Faced by imminent doomsday, caused by a global flooding wiping out all of humanity, the US government, corralled into what remains of Colorado, launches one starship with 80 people on board (depleting its remaining resources). The spacecraft uses a newly developed warp-drive to explore nearby exoplanets. Asking 80 people to survive for decades in a tiny spaceship asks for trouble and intergenerational and other personal conflicts arise. The groups splits up, one settling an unpromising earth-like planet around 81 Eridani, one returns to the flooded earth while one travels even further to make planetfall elsewhere. Despite the cataclysmic events that wipes out billions of people, Baxter has an eye for the details of plausible human interactions.
