Shout-Out: Tabula Rasa by Kristen Lippert-Martin

Sarah starts a crazy battle for her life within the walls of her hospital-turned-prison when a procedure to eliminate her memory goes awry and she starts to remember snatches of her past. Was she an urban terrorist or vigilante? Has the procedure been her salvation or her destruction?

The answers lie trapped within her mind. To access them, she'll need the help of the teen computer hacker who's trying to bring the hospital down for his own reasons, and a pill that's blocked by an army of mercenary soldiers poised to eliminate her for good. If only she knew why . . .
