Generation Ship: Escaping a Dying Sol System

When Sol stops being survivable, humanity's last real option is a single ship built to carry a fraction of its people out — and generations of their descendants to actually finish the trip. These are the books following the GSS Intrepid's escape from a dying Sol System: getting it built and launched over the objections of everyone with something to lose, surviving the saboteurs and near-disasters of the voyage itself, and the decades of unglamorous work it takes to turn a ship full of refugees into the founders of somewhere new.
