Publisher's summary
It's time the truth was told. About UNIT. About the Cybermen invasion. About the so-called 'Doctor'. About what happened all those years ago, at Warlock's Cross. About the man they keep locked up in a cage, in a secret prison...

It's time. Because UNIT scientific adviser Elizabeth Klein is going to help ensure the truth is brought to light.

Today's the day... that UNIT falls.
