SAY BOO TO PENNY FOR ME (1998, Longman, an imprint of Pearson)
Set in the near future, three close girlfriends are unwittingly drawn into a complex plot of politics, corruption and drug trafficking after helping apprehend a man who has overdosed on a dangerous new narcotic. As they are drawn in deeper, they discover that the comfort of living in a consumerist information age comes at a high cost, part of which is the identity microchip implanted in every citizen at birth.
