Can a man with no future surrender his heart to a woman with no past? He names her Sunshine for the gold of her hair, the sparkle in her eyes and the brightness of her smile, but the head injury she suffered leaves her with no memory. Why was she riding alone across the grasslands of the Wyoming Territory? Was there trouble at one of the isolated ranches? Was she riding for help? Fleeing from danger? Or after something else entirely? As a bounty hunter, Howard "Gunn" Gunnarsen seeks justice for victims of killers and thieves, but justice for his own family eludes him. He can neither forgive himself nor abandon his pursuit of the man who murdered his mother and dishonored his sister. How can he possibly consider a future with the charming young woman he rescued? Knowing her, how will he ever be able to ride away?
