Ark

Resumen

Ark is a 2009 hard science fiction novel by English author Stephen Baxter. It is a sequel to his 2008 novel Flood. Ark deals with the journey of Ark One, which Baxter has revealed to be a starship, and the continuing human struggle for survival on Earth after the catastrophic events of Flood. Ark is the last novel in the series, but it did not complete the story begun in Flood: this was accomplished through three pendant stories, which are described in the plot summary below.
Being hard SF, Ark contains many references to unrealised or hypothesised technology, physics, and hypotheses about extraterrestrial life. Baxter credits several books and academic works in an afterword: See "Scientific background" below.
