About This Book
Samuel digs through the hot Badlands, his heart pounding as the giant dinosaur bones start to peek through the dirt. Just when he thinks he's found the Black Beauty, a shadow moves nearby—someone else is after the same treasure! What will happen when their paths collide?
Themes
Quick Assessment
Set in the late nineteenth-century Badlands, this adventure follows rival expedition teams racing to excavate a giant dinosaur skeleton, with a teenage fossil hunter and a professor's daughter forced to choose between competing and cooperating. Expect real danger and peril, bitter family rivalries, and a forbidden romance that stays mostly in longing and tension rather than explicit content. Its treatment of period prejudice and limits placed on women makes it a good springboard for discussion.
