The Tardis lands the time travellers on the deserted observation deck of a skyscraper-like building. Giant screens show programmes about an evacuation procedure and reveal that "Zero Time" is an estimated 35 days away.
The TARDIS crew arrive in the city of Arkhaven on a world whose final days are approaching. They get caught up in the events, but not everything is at it seems...
Possibly if the revelations of what is really going on were less unpleasant I might have enjoyed this book more. In general, I have enjoyed Christopher Bulis' Doctor Who novels and, while this one is well written, I just didn't like it. I'm not certain why. It may be nothing more than being too dark for my mood at the time.
But I'm still giving it 3 stars, so I must have liked something!
