When Katherine Bell learns that critically endangered animals from Africa, India, and the Middle East, are being raised on modern-day Texas ranches, the widow decides to sell her home in Alpine and purchase a house on thirty-two acres overlooking hills and valleys above the Guadalupe River in the Hill Country of Texas. Her plan is to raise exotic animals in a beautiful location while hoping her new chapter leads her to find love again.

After she hires the handsome, but much younger Wolf Abbot to become the resident foreman of her newly-created ranch, they form an unconventional bond in their appreciation and concern for one another, exotic animals, and the ranch. As animals from various parts of the world come to live on the ranch-including a Kudu bull that steals their hearts-Katherine and Wolf's bond deepens and eventually transforms into a happy marriage that defies the norm in their age difference and backgrounds. As they continue living their dream, neither has any idea that a killer is on the loose and that their beloved Kudu is about to play an important role in catching him.

Kudu is the narrative account of a widow turned exotic animal rancher as she encounters rustlers, killers, friendships, heartbreak, and love in her newfound way of life.
