Venusian Lullaby by Paul Leonard

Venus is dying, when the Doctor and his companions Barbara and Ian arrive, they find an ancient and totally Alien society on the brink of destruction. A conflict is escalating between those who accept death and those who strive for salvation and survival.

Then a hope emerges, a race arrives offering to transport the entire civilisation to the safety of Earth, three billion years before mankind is due to evolve there. Are the newcomers’ motives as pure as they appear? And will the Doctor allow them to save his oldest friends by sacrificing the future of humanity?
