Della Hughes longs for adventure and for freedom from the strictness and austerity of 1870s Boston society. When her uncle and guardian, General Clint Logan, uses his fortune to purchase property in Colorado and set up a horse ranch selling remounts to the western army, Della decides she must accompany him and his family to the West. Along the journey, Della encounters more adventure than she bargained for.

Rustlers, Indians, and rattlesnakes add danger to the trek. A persistent cavalry captain who believes Della would make him the perfect wife and a Cheyenne chieftain's son who tells her she's brought sunshine to his heart complicate her life. And the handsome army scout who ramrods their wagon train guards a secret from his past that makes him believe he's not worthy of loving Della. She must meet the challenges of the West and convince the man of her heart that love is worth risking everything to gain.
