One doctor saves lives from behind a screen. The other saves them with his hands. When the world ends, they are each other's only hope. Dr. Felix Müller trusts his gut, and his gut tells him the horrifying new illness tearing through his Hamburg ER is no ordinary flu. When his superiors ignore the mounting body count, Felix risks his career on a single, desperate email to a reclusive, brilliant epidemiologist who is his last resort. Dr. Erik Lindqvist trusts in data, not gut feelings. For the reclusive scientist, emotions are a liability. He arrives in Hamburg expecting to correct a flawed analysis, but instead finds a city on the brink of collapse and a frontline doctor whose fiery compassion threatens to shatter the walls around his heart. Forced into an uneasy alliance, the two men are the city's first and last line of defense. But as the virus consumes Hamburg and military law is declared, their professional friction ignites into a desperate and dangerous intimacy. In the quiet moments between disasters, they find a connection that could be their only comfort-or a fatal distraction. As the death toll climbs and the city is sealed from the world, they are in a desperate race for a cure. But the greatest threat might not be the evolving pathogen-it could be the terrifying choices they are forced to make about how much they are willing to sacrifice... and who. Outbreak Protocol is a gut-wrenching, epic MM romance set against the backdrop of an apocalyptic medical thriller. A perfect story of opposites attract, hurt/comfort, and the found family that can rise from the ashes of the world. Prepare to have your heart seized.
