Gridlock - Revenge and Zombies, #1

In a dystopian world where the rich get richer and the poor struggle to survive, Tessa is a mad scientist. Or, more accurately, she's a pissed off one. Her father was killed for sport by the wealthy and ever since, Tessa's had one goal and one goal only -- revenge. Wanting to watch the world burn, she creates a virus no one has ever seen before. One that will turn the evil rich into mindless zombies.
There's only one problem. The virus doesn't work on the one man Tessa wishes she didn't know all too well: Rory. When her plans go awry, Rory and Tessa are forced to work together to survive. But can survival ever turn into something more?
