This story is a direct sequel to Available at the Library, that short story should be read first. Narcotics and self harm tags are for one scene near the end that can be skimmed over.

Sleep. A fleeting goal in the hot nights of Summer, out of reach, fitful when it does come. The university is closed, the library is near empty. Wiser ponies retreat to cottages on the mountain, or away from Canterlot altogether. Those that remain in the magic city lie in bed, and dream of strange things shimmering in the heat.

Floating in the dreamscape, those strange things watch and begin to file their teeth in anticipation of the coming hunting season.
