Catherine Wilder was a strange girl, lovely but lonely. Sir Henry Wilder, her father, was the kind of eccentric, medical researcher who preferred to work in complete isolation. Catherine withdrew deeper into herself as the oppressing loneliness of her father's remote mansion weighed upon her mind.
When she first heard the voice she wondered whether the mansion was haunted, then she feared for her sanity. But it was neither madness nor the supernatural which threatened her.
Mezak appeared to her suddenly in the twilight of the mansion's gloomy corridors. He was more romantic than her wildest dreams. Although some of his language was beyond her understanding at first, it gradually became possible for them to communicate. Mezak was from the future, the remote future, but Catherine slowly realised that she was in love with him! Her father's strange research into super-freezing and suspended animation gave her only a remote chance of reaching him, but she was prepared to take that chance. As Catherine placed herself in the freezing chamber, numbness and darkness crept over her.... Would she ever open those beautiful eyes again?
