Sip

It started with a single child, and quickly spread: you could get high by drinking your own shadow. At night, lights were destroyed so that addicts could sip shadow in the pure light of the moon.

Gangs of shadow addicts chased down children on playgrounds, rounded up old ladies from retirement homes. Cities were destroyed and governments fell. And if your shadow was sipped entirely, you became one of them, had to find more shadow, at any cost, or go mad.

One hundred fifty years later, what's left of the world is divided between the highly regimented life of those inside dome-cities that are protected from natural light (and natural shadows), and those forced to the dangerous, hardscrabble life in the wilds outside. In rural Texas, Mira, her shadow-addicted friend Murk, and an ex-Domer named Bale, search for a possible mythological cure to the shadow sickness—but they must do so, it is said, before the return of Halley's Comet, which is only days away.
