In 1883, as the final spike of the Northern Pacific Railroad is driven into the ground, completing the iron road through the heart of Lakota country, Black Moon's nephew Storm carries the war lance into battle against the railroad. But with his abduction of a railroad magnate's niece, the reckless warrior gets more than he bargained for.
High-spirited New York society girl Eliza Prentiss grudgingly accompanied her uncle to the wilds of Montana Territory to commemorate the completion of the railroad, but with the ceremony over, she is eager to return to civilization. When her train is attacked by Indians, she is taken captive by one of the renegades and brought to his hideout.
Struggling to come to terms with a painful past and the changing world around him, the only thing that can soothe Storm's vengeful heart is love, but his efforts to court the fiery white woman in the hope of winning her love are dashed by her hatred.
As weeks go by and Eliza's attempts to escape are thwarted, she is reluctantly drawn into the Lakota world and into the arms of her captor, who awakens within her feelings she has never known.
Can the love that ignites between these two wild hearts survive when her ruthless uncle summons the military to track down her abductor and teach him a powerful lesson and when a lie forces Eliza to make a heartbreaking choice?
