Dr. Persephone (Seph) Smith is a psychologist with enhanced empathy, allowing her to feel the emotions of others. But her gift comes with a price. Plagued by nightmares and insecure in her work, Seph absorbs the suffering of her patients by day and swills tequila by night.
When Seph is deployed to an abandoned air hangar turned medical shelter during a massive hurricane, one by one, as the wind howls overhead, staff and evacuees disappear into the dark recesses of the vast space. The missing return as mutilated corpses. The living, trapped in the shrieking metal structure by the storm, descend into varying levels of paranoia and madness.
Seph, as both counselor and detective, must determine who, or what, is preying on them. Is the panic and mayhem "shelter shock," as the lead physician, Anne Parrish, insists? Or is everyone, Seph included, in danger of losing their minds--and their lives?
