Messenger tells the story of twenty-something journalist, Alana Peterson, who is convinced she's found her big break when she meets Messenger, a mysterious old woman who delivers life-changing messages to seemingly random people all over New York City.

Alana investigates, trying to determine if Messenger is a crazy homeless woman, a shaman, an angel, or the prophet the planet needs to save it. Messenger channels her messages and knows exactly to whom to deliver them. How? Alana realizes it's not always the content of the message but the timing in a person's life that creates the Clinamen— the slight swerve-that changes everything. Can a few words change a life? A city? The world?

Through a series of mistakes, Alana bends the trajectory of the story to tragic results. Finally, Alana discovers what her journey with Messenger has really been all about.
