It's from a book I'm reading called "Stung" Basicly, Fiona wakes up, and her house is in ruins. The backstory is that scientists modified bees so they wouldn't go extinct. HOWEVER. This made their sting deadly to humans. So they made a vaccine for the bee sting. HOWEVER. The shot makes them insane and gives them mega strength. Basicly makes them animals. So they put a tattoo on those who got it. 1 shot= 1 spider leg 2 shots- 2 spider legs and so on and so forth. The most you can get is ten. The more you get, the crazier you are. Fiona got ten, but was cured. But nobody knows that, so they consider her dangerous.
RAIDOACTIVE FITS THIS BOOK SO WELL!!!! :D
