On winter solstice, the birds disappeared, and the mist arrived.

The inhabitants of Nebulah quickly learn not to venture out after dark. But it is hard to stay indoors: cabin fever sets in, and the mist can be beguiling, too. Eventually only six remain.

Like the rest of the townspeople, Pete has nowhere else to go. After he rescues a stranded psychic from a terrible fate, he's given a warning: he will be dead by solstice unless he leaves town - soon.
