Montana Territory 1867 ~ When Laura Hewett follows her father out of the mountains she never expects to lose him to an avalanche before they reach their destination of Helena, in the Territory of Montana. With the help of her friend Raven Quiver, Laura arrives at the Prickly Pear Ranch on her sixteenth birthday. Her life changes forever when she learns that the man who raised her was not her real father. Daniel Hewett stole her mother and her, leaving behind a twin sister, Lilly.

Lilly Rolston is spoiled, possessive, demanding, and uncaring; all traits she leaned well from her father, Gerhard Rolston. Lilly is furious to find out not only does she have a twin sister, but she now has a half-Blackfeet brother, Jason Rolston. If it's true, then she no longer is the sole heir of the Rolston Prickly Pear Ranch as well as the Rolston rich gold-producing Golden Eagle Mine. This is not the sixteenth birthday surprise she was hoping for.

Betrayed by Lilly, Andy Meldrum is bent on revenge and kidnaps Laura. Upon learning he has taken the wrong girl, he goes back and captures Lilly. He'll trade the pair as slaves to the Blackfeet; putting the high and mighty Lilly Rolston in her place.

The young women quickly discover they are nothing alike. Laura, the rough and wilderness savvy one is appalled by her prim and proper, as well as self-important counter-part. Lilly is likewise appalled by the ill-speaking, ill-dressed, and ill-mannered woman who is now claiming a place in her life.

After sixteen years destiny brings them back together, while fate works against them in the challenges of survival. It quickly becomes apparent the women must learn to trust and rely on each other. Unexpectedly a strong love builds, connecting the sisters and the men destiny chose for them. This is a gripping tale of endurance, growth, and the bonding ties of twin sisters.
