In 1891, during a voyage to the uncharted isle in the Furneaux Islands near Tasmania, the sixth Earl of Stanbury discovers a saber-toothed tiger thought to have been extinct for more than 10,000 years—a find that will astonish the world and bring great acclaim if he is able to return to England. Learning of the earl's suspicious disappearance, Lady Samantha enlists the assistance of professor Christian Badia—a noted zoologist and tracker specializing in wild cats who, unbeknownst to Lady Samantha, has a dark past—to join her in a dangerous expedition to rescue her uncle. Despite knowing his notorious reputation as a recluse, Lady Samantha finds herself drawn into a world of physical passion with the enigmatic man she becomes convinced is her soul mate. When the professor embarks on his own treacherous assignment, Lady Samantha fears she may forever lose her newfound love. Unable to simply stand by, Lady Samantha launches her own investigation at great peril to herself.
