Hunter Miller sees demons. The terrifying shadows engulf him and everyone he knows--yet nobody else notices their presence.

Hunter can't escape them, so he sets out to understand them. Why do they follow him? What are they trying to tell him?

In this first installment of the Master of Perceptions series, pre-teen Hunter discovers that every sensation the demons produce--whether it be sight, sound, texture, flavor, or smell--has a different meaning. And that by breaking this code, he just might be able to harness their power.
