"This range of classic Target audiobooks continues to go from strength to strength..."
It is ten million years in the future, and the Earth is about to plunge into the Sun. A gigantic Space Ark has been launched, to take the last of humanity to a new life on the planet Refusis II.
Accompanying the humans on their journey are the Monoids, strange reptilian creatures from an alien world.
When the TARDIS materialises on board, the Doctor and his friends are greeted with suspicion, which soon turns to open hostility when Dodo inadvertently infects the Ark's crew with a long-forgotten virus: the common cold.
It is an accident which will have a terrible effect on mankind, an effect which will last for seven hundred years...
Peter Purves, who played Steven in the BBC TV series, reads Paul Erickson's complete and unabridged novelisation of his 1966 TV serial, first published by Target Books in 1987.
