A Doctor Who full-cast audiobook adventure starring actor Colin Baker, who is known for playing the Doctor in the Doctor Who television series between 1984 to 1986. The year is 16127. Four decades have passed since the colonists of Nerva Beacon returned to repopulate the once-devastated planet Earth—and the chosen few are finding the business of survival tough. Far beyond the sterile safety of sanitised Nerva City, transmat scientist Roger Buchman has brought his family to an island surrounded by what they once called Loch Lomond, hoping to re-establish the colony he was forced to abandon many years before. But something else resides in the Loch. A pestilent alien infestation that the Doctor, beaming in from Nerva City, remembers only too well from his time aboard the Beacon... The Wirrn are back. And they're hungry.
