Garden City, Kansas, 1888.

Unlucky in love, the Spencer sisters Allison and Rebecca have resigned themselves to a spinster lifestyle, replacing their thwarted romances with work, family and friends. But Cupid isn't finished with them, and new chances for love are right around the corner.

However, danger also lies in wait for the sisters. A band of murderous train robbers has threatened deadly vengeance on the whole town, and a more personal threat stalks one of the sisters, intent on her destruction.

When promises fail and danger looms, can love protect the sisters from the forces that seek to harm them?
