A mostly-decent collection of stories written on the theme of superstition. My favorite was Nicholas Royle's "Glory," an unsettling story about an amateur wedding photographer who keeps seeing something strange in his camera's viewfinder. The narrator has a superstition similar to one I confess to entertaining at various times in my life: that certain events exist in a sort of quantum state, and don't become definite until you observe--or choose not to observe--them. Another standout was Robert Holdstock's "The Silvering," in which a man is determined to discover why his favorite selkie lover hasn't returned to him. ( )
