A killer stalks the streets.
Simone LeBeau is fearless. A messenger for the Hermes Guild, she travels via the rooftops delivering letters and parcels with the grace of a freed bird. A guardian to a small orphaned girl, Simone does what she must do to survive in a world where the citizens of Dark Town are being murdered by a killer called the Heart Thief.
She is caught up in a situation she can't control.
The Heart Thief murders a woman a few feet away from Simone's front door. No one else seems interested in finding justice for her or any of the other victims. But what happens when the killer turns his attention to someone close to Simone?
