Up until two weeks ago, the Plague Saint of Devil's Pass was a real doctor. But when Winter learned he was only saving the rich and planned to let her mother die, she confronted him. And killed him. The death was an accident, but taking his place to save lives was a choice.
Then, Winter's forced to kill again to save her brother. Her double life, already doomed to fail, is complicated further when her assistant insists on tracking down the murderer. Attempting to cover her tracks leaves Winter tangled in a political web. All the while, people are getting sicker, and trying to find the cure leads her to an enemy far smarter and more dangerous than she is.
