People are dropping like flies in Dr. Emma Steele’s ER, and nobody knows why. A new disease? Medication errors? Poisoned oxygen? She must find out,  even though her job is in peril, her daughter disappeared and she’d rather be home drinking wine.

A mercy killer? But why would he kill a healthy patient? Is somebody framing her nurses? Or herself?

Dr. Steele risks her career and her life to stop the murders. She gets closer and closer. Until she gets too close.
