Brazilian federal enforcer Ana Mendes has devoted her life to maintaining public order in a post-pandemic Brasilia where half the population is terrified of catching something and the other half seems hell bent on tempting it.

But when an ambulance carrying a baby vanishes, her rule to Avoid Close Contact—warned on signs across the city—is tested when she’s partnered with consultant Will Hardwin, an ex-Army medic, who’s spent the years since the outbreak trying to atone for his past.

Their investigation to find the missing child takes a bizarre turn when they uncover a string of unexplained disappearances that locals attribute to a phantom—some say a demon—from myth. Now it may be after Ana and Will. Trusting in each other is the only way to destroy the cunning enemy on their trail before it kills them–and unleashes a deadly new plague upon the world.
