When astrobiologist Jules Rammis returns to Earth after saving the Terran colony on planet Tartarus from a demented member of the Loranth race, he hopes to spend some quiet time with his six-year-old daughter Lisa whom, he finds, has inherited his own telepathic skills.
Their plans change when a powerful denizen of planet Halcyon summons them both to his pristine world to destroy a Terran ravager, the Dream Czar of Halcyon. Jules, reluctant to take his daughter with him on such a dangerous mission, soon learns that the alien will not take no for an answer. After the infuriated creature threatens to
kill them both and destroy the treacherous community of Terrans on Halcyon, Jules has no other option but to accept the mission.
Will Jules be able to keep her daughter safe, to complete the mission and save the inhabitants of Halcyon before it's too late?
