Synopsis

There have been many ways to invade the Earth, and the Eleventh Doctor has seen them all – or so he always thought. And then the human race wakes up one morning and discovers the world has been overrun by small cubes, which then proceed to do nothing at all. A plan is afoot, humanity is endangered – but by what and how and, above all, when? Thus begins the Year of the Slow Invasion.

For the first time in his world-saving career, the Doctor has to call upon one of the least of his virtues: patience. And the Ponds face something possibly more terrifying than any world-ending apocalypse: the Doctor is moving in!
