Derik is on the run. Not from the deadly epidemics on the rise in New Zealand but from the ruling government and its efforts to wipe out disease. The authorities have begun Endorsement: a nation-wide drive to implant a device in every citizen, to regulate body chemistry and control emotions. It’s a social experiment the whole world is watching. But Derik wants to think - and feel - for himself. Trying to find shelter, stay hidden, and keep himself alive, he soon discovers he’s not the only one to have turned fugitive.
