Doctor Who : The Forgotten Army

New York - one of the greatest cities on 21st-century Earth...But what's going on in the Museum? And is that really a Woolly Mammoth rampaging down Broadway? An ordinary day becomes a time of terror, as the Doctor and Amy meet a new and deadly enemy. The vicious Army of the Vykoid are armed to the teeth and determined to enslave the human race. Even though they're only seven centimetres high. With the Vykoid army swarming across Manhattan and sealing it from the world with a powerful alien force field, Amy has just 24 hours to find the Doctor in the doomed asteroid mines of the Vykoid home planet. But as time starts to run out, who can she trust? And how far will she have to go to free New York from the Forgotten Army?
