Could Sasquatch be real?  Halls explores the history and theories behind the belief in a species of giant primates which haunt a variety of terrains all over the world.  She describes many recent sightings and provides a window into the world of Sasquatch tracking.  This topic will seize the attention of many children (and adults) and the information is presented clearly, openly, and attractively.  Photos and illustrations pepper the pages, demonstrating the elements Halls discusses.  Halls gets much of her information by interviewing actual cryptozoologists and other primary experts in the field.  Although generally this is a plus, there is one unfortunate inclusion: On pages 13-14, Halls includes a partial transcription of a 9-1-1 call regarding a potential Sasquatch sighting.  In the introduction, she instructs readers to ask parents before listening to a YouTube video of the call because there is strong language featured on the tape.  In the abridged transcription, however, she includes three instances of potentially offensive language, even though the implication in the introduction was that those portions would be left out of the account because of the book’s young target demographic.  This inclusion will offend some audiences.  However, the rest of the book is illuminating and engaging and demands its place on library shelves, particularly in libraries which appreciate its Pacific Northwest focus.
