The Backup Crew

Zander Nelson, formerly known as Phantom and a member of a superhero group called the Backup Crew, loses his job and his apartment—due to a bomb—in one afternoon. 

He finds refuge with his ex-girlfriend and teammate, Millie Lennet, formerly known as Mule, but her apartment is also torched, and they realize that someone has a vendetta against them. 

Searching for clues nets them nothing. Their former leader, Andrew Shorter—AKA Blaster—is missing, and their former teammate, Glen Fooks—AKA Substance Abuse—is dead, courtesy of another bombing.

Zander's notion of justice is sorely tested, and once he puts the clues together, he realizes that things aren't so black-and-white anymore. He also realizes that if the real culprit isn't caught, he and Millie might not live another day.
