A Geek's Worst Nightmare: Going Back to High SchoolReturning to high school is not something I ever wanted to do over it was awful the first time around. So why do I have to go back as part of a new undercover assignment? Because the universe loves playing jokes on me, obviously. I've been ordered to go all 21 Jump Street and track down the students who are breaking into the computer system, changing grades, and causing all kinds of havoc. Although I'm not thrilled about my new gig, at least it gives me something to do other than worry over the fact that I now have a boyfriend. And no freaking idea what to get him for Christmas. Or it did give me something else to worry about, until I stumbled across a more sinister threat. I was shocked to find distinct traces of a group of international hackers inside the network. Why would dangerous cyber mercenaries be interested in a high school in the middle of Washington, D. C.? What exactly have I gotten myself into? Don't miss Lexi's first case in No One Lives Twice!
