In the aftermath of DARK NIGHTS: METAL, the DC Universe has been forever changed as new heroes are called out of the shadows. Amid this all is Janet Fals...Firebrand! Once a paramedic dedicated to saving lives, she must now start a fight once every 24 hours to feed the Conflict Engine that’s replaced her heart. But Janet’s heart isn’t just a curse—it’s a beacon, drawing out both the mysterious Neon the Unknown and the seductive, malevolent Bad Samaritan. One of them wants to cut out her heart, the other wants to save it—but neither of them knows the true danger hidden within that will kick off a superhero manhunt ranging from Thanagar to the deepest heart of the Dark Multiverse!
