Venusian Lullaby is an original novel written by Paul Leonard and based on the long-running British science fiction television series Doctor Who.
When the Doctor, Ian and Barbara arrive on Venus, they find an ancient civilization on the edge of extinction.
Then a space-traveling race arrives, offering to rescue the Venusians by transporting them to Earth, three billion years before man is due to evolve.
But are the visitors' motivations that simple, and can the Doctor allow the sacrifice of humanity's future to save another species?
The title refers to a favourite tune of the Third Doctor's, the "Venusian" words of which were first heard in The Dæmons, where the first line is said to mean "Close your eyes, my darling, (well, three of them at least)".
