Rachel Sexton is a senior data analyst working for NRO under director William Pickering. She is the daughter of Senator Thomas Sedgewick Sexton and his deceased wife Katherine. She was involved in a complication with NASA during her father's campaign. She is in her mid-thirties, single, very smart and resourceful. At the end of Deception Point, she begins a relationship with oceanographe Michael Tolland.
Rachel is described as being very similar in looks to her father - same piercing gray gaze, classical, sophisticated posture that airs a lively nobility, but she carries herself with grace and modesty. She has a well-built and well-endowed physique, light brown, shoulder-reaching hair with luscious ringlets curled inwards.
