Late blooming Sam Rains finally gets her first period at the annual all-night skate. At first a triumph, her new condition brings strange side effects. An erie electrical problem has the kids teasing about “the Boogeywoman,” a local legend, a sorceress who feeds on men’s souls and eats little girls. When a friend leaks about Sam’s period, the boys tell her she’s fair game for The Boogeywoman. With an expected tryst derailed, Sam leaves the skating rink in a fever only to meet the legend in the flesh. Instead of a monster, Sam finds a mother, a goddess, a mentor--opening the door to womanhood.
