I just finished Last Seen by J.T. Ellison, and like her other books, it was a thrill ride from beginning to end. The dark possession, the twisted manipulation, the cult-like dread—they’re all here, woven into a family mystery that grips you and refuses to let go.
Summary + Characters
Halley James is a forensic scientist whose life starts to collapse. She’s just lost her job, her marriage is unraveling, and when her father becomes gravely ill, she returns to her childhood home. That’s when she learns her mother’s death—long thought to have been a car accident—was actually murder. And that her half-sister, Cat (Catriona), was blamed. But Cat’s story is far more complicated: she was institutionalized, disappeared, and Halley’s dad kept secrets. Driven by the truth, Halley follows leads to Brockville, Tennessee, a place that feels perfect on the surface but hides something terrible beneath.
Other key characters include:
• Quentin – Halley’s father, loving but unreliable, bound by lies.
• Cat / Catriona – the half-sister shrouded in mystery; possibly dangerous, possibly a victim.
• Theo – Halley’s estranged husband, straining under loss, expectations, and what Halley is becoming.
• The Brockton family and the inhabitants of Brockville—especially its founder, sons, and those who maintain the town’s outward utopia but underpin a sinister reality.
What Works
• The moment the “male voice” whispers “come here. Come closer.” hits—you know you need to pay attention. It sets a creepy tone that lingers.
• The tension keeps building. The past and the present intermingle, memories are distorted, and trust is always fragile.
• Ellison’s style is intoxicating: once you’re in, it’s hard to pull out. You get drawn into Halley’s doubts and fears, and the story unravels at just the right speed.
• I especially liked how the cult presence isn’t overt from the start—it seeps in. The “perfect town” trope is done well, with creeping menace rather than sudden jumps.
What Doesn’t Always Land
• There are moments when character relationships and situations feel a bit overstuffed—too many threads at once, which can get confusing.
• Some revealed motives or secrets feel slightly stretched, or delayed in a way that asks you to suspend disbelief more than comfortable.
• The voices (especially from Cat, Halley’s father, the Brocktons) are strong, but at times the “darkness” feels so orchestrated, so layered, that the fine line between thrilling and overwhelming is nearly crossed.
Final Thoughts
This is exactly the kind of book I want from Ellison: intense, twisty, emotionally heavy, with enough psychological horror and family betrayal to keep you up at night. If you like books where reality is unreliable, memories are weaponized, and cults aren’t just whispering rumors—you’ll love Last Seen. Let the story pull you in. It gets you wrapped up immediately, and even when things nearly trip over themselves, the payoff is worth it.
⭐️⭐️⭐️⭐️ / 5 — Definitely a 3.5 rounded up to 4. A dark, riveting read. Some moments of overload, but overall completely absorbing
