Plastic Smile (Russell's Attic Book 4)
Cas Russell, antisocial mercenary, has decided to Fight Crime. With capital letters, like in one of her friend’s comic books.<br /><br />After all, she has a real-life superpower: with her instantaneous mathematical ability, she can neuter bombs or out-shoot an army. And it’s Cas’s own fault violence has been spiking in the world’s cities lately — she’s the one who crushed the organization of telepaths that had been keeping the world’s worst offenders under control. Now every drive-by or gang shooting reminds Cas how she’s failed, and taking out these scumbags one at a time is never going to be enough.<br /><br />She needs to find a way to stop all the violence. At once.<br /><br />But Cas’s own power has a history, one she can’t remember — or control. A history that’s creeping into the cracks in her mind and fracturing her sanity . . . just when she’s gotten herself on the hit list of every crime lord on the West Coast.<br /><br />Cas isn’t going to be able to save the world. She might not even be able to save herself.
