Once a creature is extinct, it's gone forever, isn't it?
Not any more - as a butterfly from the past proves. The physicist mother of Kizzy and Fraser Tye has invented an amazing time machine that can travel back into the past, snatch a plant or animal now extinct and bring it back to the present.
It's a wonderful achievement, a real scientific breakthrough. But the machine - "Rye's Apparatus" - has a horrifying potential. Suddenly Kizzy and Fraser find themselves caught up in a terrifying spiral of events - events that lead finally to a monstrous demand from a sinister and violent organisation . . .
Winner of the 1995 Earthworm Award.
