One With You

The fifth and final installment of the Crossfire series opens in Manhattan, where Eva Tramell and her husband, Gideon Cross, a billionaire mogul, are reconciling after a painful separation. Eva forced the split after Gideon hired her boss, Mark Garrity, away from her advertising agency without consulting her. Gideon has just made a major breakthrough by calling Eva to share the details of a violent nightmare rooted in childhood sexual abuse by his former therapist, Hugh. Both Eva and Gideon are survivors of childhood sexual abuse, a shared trauma that simultaneously bonds and destabilizes them. They have been secretly married for about a month after eloping, and they attend weekly couples therapy with Dr. Lyle Petersen.

Eva begins dismantling the walls she has built around her life. She confesses the elopement to her mother, Monica Stanton, whose anxiety over the prenuptial agreement is calmed when Eva's stepfather, Richard Stanton, reveals Gideon sent the prenup weeks earlier with terms exceptionally generous to Eva. Eva also calls her father, Victor Reyes, a police officer in California, whose devastation at learning she married without telling him reduces Eva to tears. Gideon arrives, takes the phone, and accepts full responsibility. Eva then submits her resignation at Waters Field & Leaman, recognizing that clinging to her independent career is straining her marriage beyond what it can sustain. She sends Gideon two dozen white roses signed "Mrs. Cross."

At couples therapy, Dr. Petersen identifies a dangerous pattern: Both Eva and Gideon are manipulating each other to accelerate change on a timeline that could trigger their self-defense mechanisms. Gideon tends to dissociate, while Eva tends to blame herself and subvert her own needs. Eva articulates that her right to make her own choices is critically important given her abuse history, and Gideon apologizes for failing to see this connection when he hired Mark. They agree to a new dynamic of open communication and mutual compromise. Eva then proposes they abstain from sex until the public wedding, arguing they must stop using physical intimacy as a crutch. Gideon resists but concedes. Eva chooses September 22, Gideon's birthday, as the date.

Eva pitches a media strategy to counter a tell-all book by Gideon's ex-fiancée, Corinne Giroux: Stop hiding and release candid photos to fill the public's appetite, rendering Corinne's book irrelevant. Monica warns that inviting media attention is irreversible. At the Crossfire Building, Corinne arrives at Gideon's office with old photographs. He tells her he and Eva are married and declares this their final good-bye. When Eva arrives and announces she has quit her job, they meet in the middle of his office, symbolizing their commitment to compromise.

The couple spends a weekend at the Stanton beach house in Westport, Connecticut, where Gideon's discomfort with being absorbed into Eva's family erupts. Monica's warm embrace and Stanton's hug trigger near-panic in a man whose mother, Elizabeth Vidal, refused to believe his abuse and whose father died by suicide. Eva delivers tough love: If he did not want in-laws, "you should've married an orphan" (96). That night, they share a bed despite the danger posed by Gideon's violent nightmares, a condition his therapist calls atypical sexual parasomnia. They bathe together and make out without having sex. Gideon sleeps through the night without incident for the first time, a pivotal breakthrough.

Eva confronts Anne Lucas, a psychologist and Gideon's dangerous ex-lover whose husband once lied about finding signs of abuse on young Gideon to protect Hugh. Anne has been targeting people in Eva's circle, approaching her best friend and roommate, Cary Taylor, in disguise. Eva ambushes Anne outside her office. Anne sneers that Gideon is a "monster" in therapy since childhood. Eva fires back, declaring herself "the beast" (148). Anne retaliates by filing false harassment charges, which Gideon's attorney, Arash Madani, gets dismissed.

Eva surprises Gideon with a beagle puppy named Lucky as a one-month anniversary gift. Lucky proves significant when the dog wakes Gideon from a nightmare by barking and scrambling onto the bed. In the late-night call that follows, Gideon reveals his stepfather, Chris Vidal, has filed for divorce from Elizabeth, likely because Chris learned the truth about Hugh.

Arash discovers that Deanna Johnson, a journalist Gideon once slept with, is ghostwriting Corinne's book. Eva suggests hiring Deanna at Cross Industries to bind her to nondisclosure clauses. When a viral nightclub photo threatens scandal, Gideon appears on a daytime talk show, reveals their marriage, and proves the photo was digitally altered. Eva watches with her mother, who becomes pale and distressed during the interview. Meanwhile, Gideon's driver and bodyguard, Angus McLeod, uncovers that Eva's mother has been living under a stolen identity for over 25 years. Gideon withholds the information until he has the full picture.

Gideon confronts his mother in a devastating scene. He says the words he has never spoken directly: "I was raped" (338). He describes the abuse in explicit terms and accuses Elizabeth of knowing the truth and choosing to ignore it. She denies everything and walks out. He tells Eva the hope his mother would acknowledge the truth is finally dead. He then asks Chris to be his best man, wanting someone who knows everything standing beside him at the altar with no pretense.

At a black-tie dinner honoring Gideon's philanthropy, tragedy strikes. As they exit, a man named Roland Tyler Hall opens fire. Gideon tackles Eva to the ground; she loses consciousness under the weight of security personnel piling on top of them. Monica steps into the line of fire and is killed. Gideon lies to Eva overnight, telling her the sounds were a car backfiring while he arranges support. He tells her the truth the next morning. Detectives reveal Hall was obsessed with Gideon and that his psychiatrist was Anne Lucas, operating under an alias. Anne deliberately manipulated Hall toward violence and is arrested.

At Monica's memorial, the Stanton family's head of security, Benjamin Clancy, reveals the full truth to Gideon. Eva's mother was born Lauren Kittrie and grew up poor in Texas with a twin sister, Katherine. A man named Jackson Tramell orchestrated the gang rape of Katherine, causing permanent brain damage. Lauren married Jackson to fund Katherine's care. When Lauren became pregnant with Eva by Victor, Jackson tried to beat her into miscarrying. Lauren killed him, and the Tramell family covered it up in exchange for her disappearance. She assumed the identity of Jackson's sister, the real Monica Tramell, and spent decades marrying wealthy men to fund Katherine's ongoing care. Gideon accepts responsibility for Katherine and custody of the journals Lauren left for Eva.

Eva's grief finally breaks through when she dreams of her mother. The family gathers at the Outer Banks for Gideon's birthday, where Eva's paternal grandmother offers a handmade wedding dress. On the beach, with their families watching, Gideon places a diamond eternity band on Eva's finger and whispers "Crossfire" (445). The couple departs for a monthlong honeymoon at a luxury tree house hotel overlooking the Pacific, where Eva reads her mother's journals and plans to visit Katherine. In a final dream, Eva speaks with her mother and finds peace. On a sunset dinner cruise, she and Gideon toast to blue skies, the ghosts of their pasts beginning to dissolve.
