Across The Universe: Pamela Sargent and George Zebrowski

Star Trek Original Series No. 88. The Hawking left Earth during the 21st century on a one-way mission to colonise a distant world. Due to the relativistic effects of pre-warp travel, its crew has aged only 30 years while two centuries have passed outside the ship. When the Enterprise comes to the rescue of the malfunctioning Hawking, the colonists find themselves thrust into a universe and an era that has left them behind. Captain Kirk intends to help the colonists adjust as best he can - but it's not simple. The newcomers are survivors of a more violent, more paranoid time and they have brought old suspicions - and an ancient weapon of mass destruction - into a world of unexpected challenges and dangers.
