BASIC PLOT
All over the world, people are giving vent to their hatred and everywhere behaving with incredible cruelty. Even Donna has found that her friend Hettie, with her seemingly perfect life and fancy house, has unfriended her. And now, all over the world, internet trolls are dying... From the streets of London to the web cafes of South Korea and the deepest darkest forests of Rio, can the Doctor and Donna find the cause of this unhappiness before it's too late?

PREPARATORY READING
You need to be familiar with the Big Finish audio Time Reaver, although nowhere in the publicity or the text is this obvious. Amusingly, although this is a sequel to the audio, the latter was accidentally released four days later.

CONTINUITY COCK-UPS

1. Back cover: "From the streets of London to the web cafes of South Korea and the deepest darkest forests of Rio, can the Doctor and Donna find the cause of this unhappiness before it's too late?" Except that Rio is a city and doesn't have forests. The Doctor and Donna explicitly take a train from Rio into the jungle, but it takes some time.
2. Pg 121 "Just by dialling with your anger online, working on your better self, trying to eliminate your faults and listening to your conscience..." Say what? Who dials with their anger?
3. Pg 137 "But the train driver's reaction was worse: he head twisted right round, he inadvertently took his hand off the dead man's handle, just as his foot instinctively pressed harder on the accelerator in fright." This is a complete misunderstanding of how the dead man's handle works on a train. If the driver takes his hand of the dead man's handle, the train will begin to slow, regardless of any other action. He can put his foot on the accelerator all he likes, but if he's not holding the handle, the train will stop, not accelerate off the rails as it proceeds to do here. (The dead man's handle is precisely to stop trains careening out of control if the driver dies with his foot on the accelerator!)
4. Furthermore, accidentally touching the accelerator isn't enough to make the train keep accelerating, just as it isn't if you brush it with your foot in your car. The only way the entire ensuing set piece could happen is if the driver had kept hold of the dead man's handle the entire time and kept his foot on the accelerator, neither of which occur.
5. Pg 141 "'I mean, it, get your hands off me!' said Donna in a tone of voice that would have given most people pause." Why does Donna pause between "mean" and "it"?
6. Pg 164 "'But can you stop torture or hurting other people?' she shouted after him as he lightly reached the end of the log." Donna means "stop torturing or hurting other people" here.
7. Pg 275 "'Just press the blue button!' the Doctor was screaming. 'Blue button! Big blue button i have told you a million time!'" Why doesn't the Doctor capitalise "I"?

PLUGGING THE HOLES [Fan-wank theorizing of how to fix continuity cock-ups]

1. The city of Rio likes to believe it's larger than it is. Much like the geography knowledge of the writer of back cover blurbs, one suspects.
2. The Doctor's knowledge of the internet is stuck in the dial-up era.
3. Somebody messed up when designing this train.
4. They really, really messed up.
5. Donna's tone also gives her pause.
6. She'd also like him to stop torture in general, thanks.
7. The Doctor becomes very humble when he's stressed.

IN SUMMARY - Robert Smith?
This is all over the map, both literally and figuratively. Some of the comedy is very funny. Other parts beggar belief, such as the idea that the Doctor can't access his TARDIS because hipsters are using it to serve coffee, meaning he has to take planes and trains around the world. The failed logic behind the dead man's handle ruins the central set piece, and the generally high number of errors does actual damage to the book. (How exactly does a virus that's carried in the blood get transmitted through the internet? No really, I'd genuinely like to know.) And making it a sequel to something without telling us what should be a high crime against Doctor Who literature. (Seriously, not even a footnote?) But the Doctor and Donna are well characterised, which helps. Fief is fun, and the global nature of the book justifies the page count. A bit of a mish-mash, all up.
