Black and White is a 2009 superhero novel written by Jackie Kessler and Caitlin Kittredge and published by Spectra Trade Paperbacks.
Just before the transfer, Iridium disappears, working toward her own goals in a section of New Chicago called Wrecked City.
The pair come across Jet fighting Lynda Kidder, who has been turned into a heavily muscled monster.
A Publishers Weekly review states, "Both characters are intriguingly flawed: Jet suffers from insecurity, while Iridium's arrogance repeatedly gets her into trouble" and "Jet and Iridium's multifaceted relationship will appeal to all who have come to want more from their superheroes than good vs. evil and mindless battles.

"[4] In Analog Science Fiction & Fact, Don Sakers reviews Black and White and Shades of Gray, writing, "Jet and Iridium are engaging characters and their world is intriguing.
