Black and White — Jackie Kessler; Caitlin Kittredge

It's the ultimate battle of good versus good.

They were best friends at an elite academy for superheroes in training, but now Callie Bradford, code name Iridium, and Joannie Greene, code name Jet, are mortal enemies. Jet is a by-the-book hero, using her Shadow power to protect the citizens of New Chicago. Iridium, with her mastery of light, runs the city's underworld. For the past five years the two have played an elaborate, and frustrating, game of cat and mouse.

But now playtime's over. Separately Jet and Iridium uncover clues that point to a looming evil, one that is entwined within the Academy. As Jet works with Bruce Hunter -- a normal man with an extraordinary ability to make her weak in the knees -- she becomes convinced that Iridium is involved in a scheme that will level the power structure of America itself. And Iridium, teaming with the mysterious vigilante called Taser, uncovers an insidious plot that's been a decade in the making…a plot in which Jet is key.

They're both right. And they're both wrong. Because nothing is as simple as Black and White.
