Strange events and an undercurrent of tension permeate The Chichi Hoohoo Bogeyman. While secretly exploring an old fort on the South Dakota prairie, three Indian girls encounter a stranger. One of the girls playfully names him the chichi hoohoo bogeyman, after the Sioux, Hopi, and white figures used to discipline children. On a forbidden outing the girls again encounter the stranger, who starts to chase them as they run away in fear. Swearing themselves to secrecy, they become further unsettled when they return home and hear the adults talk of recent unexplained occurrences at home, perhaps driven by spirits. The most rebellious of the girls disappears before the mystery of the chichi hoohoo bogeyman comes to light.  Booklist praised the "fresh, in-tune portrayal of the girls and their families" and recommended the book for readers in grades 3 to 5. This Bison Books edition includes a new introduction by the author.
