Psychiatric nurse Phoebe Bernhardt loves her youngest brother with all her heart. When he becomes one of the first victims of a bizarre epidemic of paranoia and aggression, Phoebe will stop at nothing to save him. She'll even work with the strange, antisocial woman who literally crashed into her life.
The stranger, a software engineer named Mila, blames the plague on technology... but she's hiding something. Is Mila a possible path to a cure - or is she the cause of it all? Or will she just prove to be indifferent to the fates of thousands of people, including Phoebe's brother?
Searching for the answers will force Phoebe to face her fundamentalist religious family and her own assumptions about who she is - and drive her to the brink of death.
