Tau Zero (Berkley Medallion Book)

The epic voyage of the spacecraft Leonora Christine will take her and her fifty-strong crew to a planet some thrity light-years distant. But because the ship will accelerate to close to the spped of light for those on board subjective time will slow and the journey will be of only a few years duration. Then a buffeting by an interstellar dustcloud changes everything. The ships deceleration system is damaged irreperably and soon she is gaining velocity. When she attains light-speed tau zero itself the disparity between ship-time and external time becomes almost impossibly great. Eons and galaxies hurtle by and the crew of the Leonora Christine speeds into the unknown.
