The serpent scenario - A. J Butcher

It's utterly forbidden for students to leave the Deveraux College grounds - except on official Spy High business. The punishments are legendary and no one has gone AWOL in living memory - until Jen. Jake's convinced it has something to do with her murky past on the streets of LA and persuades Bond Team to mount a search. But instead of Jen, all
the trainee agents find in Undertown LA are rival gangs dealing in a deadly new drug known as Drac. Drac is instantly and horribly addictive, turning users into pumped up zombies with an alarming desire for fresh blood. It's going to take all of Bond Team's training to stay alive long enough to locate Jen, and more than that to shut the dealers down.

Spy High continues with: 4. THE PARANOIA PLOT (Sep '03), 5. THE SOUL STEALERS (Nov '03), THE ANNIHILATION AGENDA (Jan '04)
