The Siege of Eternity

by Frederik Pohl

The novel is set in the near future, in a world in which the United States is struggling with many problems, including weapons of mass destruction, ecological damage, crime and hyperinflation. In The Other End of Time, government agent Dan Dannerman (actually a secret agent) goes up with a team to investigate an abandoned space station in Earth orbit after messages from space aliens are received. Dannerman and the group end up getting abducted by a type of space alien called "Beloved Leaders", who conduct many experiments on the humans, including making cloned copies and vivisection. In Siege of Eternity, Earth is caught in the crossfire in a war between aliens called the "Beloved Leaders" and the Horch, which control the "Eschaton", a future which gives eternal life. The abducted humans escape and return to Earth, where they learn that their clones are already there. The returning humans bring two captured aliens, who claim that they will teach humans about alien "Beloved Leader" technology. An officer from the National Bureau of Investigation takes control of the clones. Then the aliens warn that there will soon be an invasion by the Beloved Leaders, and perhaps an invasion of the Horch too. At the end of the novel, an undercover religious militant attempts to kill the abductees.
