[Book One in the Always Series] Elena had always admired her uncle's work as a police officer and her father's work as a firefighter, Hank, and Hunter Voight were both inseparable and their kids were the same. Elena immediately joined the Marines when she turned eighteen and later rangers where she met Jay Halstead and Greg Gurwitch who would become her closest friends and shoulders to cry on when she needed them and vice versa. After receiving unexpected and startling news that changes everything for Elena, her unit chief, Aaron Hotchner, agrees to assign her to intelligence and Hank immediately agrees, especially after learning what brings Elena back to Chicago.

Chicago is a city built on secrets and Detective Wren Severide carries more than most. Wren Severide has forged a career on discipline, razor-sharp instincts, and a calm that never wavers under pressure. When Sergeant Hank Voight recruits her into the Intelligence Unit, the decision raises eyebrows. Wren is undeniably talented, but Voight's reasons for selecting her remain as guarded as the detective herself. In Chicago's most dangerous cases, success demands quick thinking, fearless action, and an eye for patterns others miss. Wren thrives in the field, her quiet intensity and analytical mind earning her the team's respect. Yet the deeper she descends into the city's underworld, the harder it becomes to keep her own history buried. Scars she refuses to explain. Secrets Voight won't reveal. Shadows that haunt her every move. As the Intelligence Unit closes in on traffickers, dealer, killers, and predators, Wren discovers some ghosts don't stay buried, and the line between justice and survival is thinner than anyone dares admit. Among those she must learn to trust is Detective Jay Halstead, a former Army Ranger carrying his own quiet burdens. Their partnership begins as wary professionalism, founded on mutual respect and the shared cost of survival. But late nights, high-stakes cases, and unspoken truths spark a slow-burning connection neither can ignore. Jay's steady presence threatens the walls Wren has built for years, and with each glance and near miss, the line between duty and desire begins to blur. TW: - Violence, gore, death, etc.
