A young boy's fear and admiration for Wolves is the subject of Minnesota author Mary Casanova's new book "Wolf Shadows". Casanova's home is near the Minnesota/Canadian border. Her surroundings often provide the inspiration for her young adult books. Her intimate knowledge of the north woods and her frequent sightings of wolves helped to spark the idea for "Wolf Shadows". Mary Casanova is not afraid to take on controversial subjects in her writing. "Wolf Shadows" explores animal rights and man's complex relationship with wolves.
