Caroline Whitaker keeps seven sisters and a wagon company moving west, her late father's route notes never far from her hands.
The trail leaves little room for uncertainty, especially the kind stirred by Thomas Reed, a careful surveyor whose maps are steady and whose attention is quieter still.
Thomas has long trusted measurements over promises, yet flooded crossings, dangerous shortcuts, missing oxen, and the daily disorder of the Whitaker sisters make him picture a future that does not end when he rides on.
A position at Fort Kearny offers the security he always believed he wanted, and Caroline must face the fear that love could ask her to release more than she is ready to give.
Thomas still has to choose between the fixed life he can plot and the woman who has shown him that direction alone cannot decide where he belongs.
