My first taste of river song. Five Twenty-Nine starts slowly, and has a slightly odd performance from a teenage girl which is almost immediately explained. There is SO MUCH intrigue and an impending apocalypse which slowly builds.

The unique threat of a time zone by time zone disaster at 5:29pm is compelling and keeps you guessing. The way the human looking android teenager fits nicely into the overall plot.

It’s a horrible, dystopian cliffhanger - but an emotionally potent one. A wonderful example of what Big Finish can do.
