A new century has begun in the Arizona Territory. Jamie Jones, eldest son of Evan and Reyna, finds his life complicated by prejudice from Easterners since he looks like his Mexican mother. But his stubborn Welsh half is determined to be accepted, so he sets his sights on winning the affection of Miss Iris Crawford, a newly arrived, aloof beauty with motives of her own. Percy Kindall lives the life of a privileged rogue in San Diego - until the day of his father's suicide. Percy learns his father's penultimate act was to post a letter to a mysterious woman he's never met, Mrs. Reyna Jones in Tucson. Percy journeys to find her, learning more about himself along the way. When he arrives in Tucson, he recognizes a kindred spirit in Iris Crawford. Distracted, he makes clandestine arrangements for their mutual satisfaction. Unaware of the avaricious manipulations of Miss Crawford, Jamie and Percy's lives collide and intertwine in a web of long-kept secrets, and complicated relationships - a legacy of blood and fire that will change everything.
