A small-town detective reopens an unsolved case, sending shock waves across generations of women in this gripping new mystery from the Edgar Award–winning author of Please See Us.
1990. In the myth-riddled woods of the New Jersey Pine Barrens, sixteen-year-old Annabelle Riley's twin sister, Sabrina, has been having an affair with a mysterious older man, and Annabelle is determined to uncover what's going on. Then, inexplicably, both sisters disappear.
In this same town years later, newly instated police chief Callie Hauser makes an arrest that unexpectedly resurrects details from a heartbreaking cold case. As she digs deeper, the past and the present collide, challenging everything Callie believes about right and wrong, who she is, and the town she's always called home.
A propulsive mystery as incisive as it is forgiving, Heather bears a visceral reminder that the truth of a woman's life is often complicated and unknowable—to those on the outside, and sometimes even to herself.

My Review
A haunting, slow-burning 1990s historical procedural.
"A razor-sharp mystery where a small-town police chief is forced to re-examine a devastating cold case from the depths of a myth-riddled forest."
In HEATHER, Edgar Award–winning author Caitlin Mullen (Please See Us delivers a deeply atmospheric, multi-generational New Jersey Pine Barrens, 1990s historical thriller mystery.
The story hinges on an ambitious female chief of police facing immense structural and personal hurdles to solve the disappearance of twin sisters.
Relentless detective vs. small-town corruption.
Elevator Pitch
Decades after sixteen-year-old twin sisters vanish from the eerie woods of the New Jersey Pine Barrens, a newly instated female police chief makes an arrest that unexpectedly reopens the cold case, forcing past and present to collide in a town built on secrets.
Setting
The story shifts seamlessly between a pivotal timeline in the 1990s and the present day. The narrative unfolds within a tight-knit, isolated community nestled deep in the shadows of the myth-riddled, dense, and fog-heavy New Jersey Pine Barrens.
Vibe
Tense, brooding, and deeply lyrical. It pairs the gritty, slow-burning realism of Mare of Easttown with the haunting, folklore-tinged dread of an isolated, small-town cold case.
Genre
Historical Mystery / Police Procedural / Psychological Suspense.
Themes
~The Presentness of the Past/Trauma
~Exploitation and Vulnerability
~Motherhood and Sisterhood
~Grit and Resilience
CALLIE HAUSER: THE SEARCHER OF TRUTH
Turning systemic skepticism into a relentless investigative crusade.
Standout Characters
~Callie Hauser: The protagonist, a newly appointed, fiercely determined police chief whose pursuit of a cold case challenges everything she knows about her town and herself.
~Annabelle and Sabrina Riley: The missing 1990s twin sisters—one protective and suspicious, the other trapped in a dangerous affair with an older man before they both vanished.
Author Writing Standout
Mullen’s signature gift for chronicling complex women shines through in her meticulous, highly empathetic rendering of the multiple points of view.
Takeaway
The absolute truth of a woman's life is often complicated and unknowable to outsiders; finding justice requires standing together to expose the monsters hidden in plain sight.
Title Significance
Heather acts as an organic and structural marker for the novel. It represents both the rough, resilient flora thriving in the harsh undergrowth of the Pine Barrens and a poignant nod to the fragile, feral nature of youth that the small town failed to protect.
Metaphor
The myth-riddled woods of the Pine Barrens serve as the central metaphor of the novel. They represent the community’s collective subconscious—a dark, tangled labyrinth where deep secrets and historic crimes are buried, yet stubbornly refuse to decay.
Why You Should Read
Read this if you are a fan of deeply immersive, atmospheric literary mysteries like The God of the Woods by Liz Moore or the work of Tana French, where the setting is just as much a character as the people navigating it.
My Thoughts
The novel succeeds beautifully in building generational tension. The 1990s timeline is perfectly captured—not just in its aesthetics, but in the raw medical and social anxieties of vulnerable teenage girls. Callie is an unforgettable lead; her grit, focus, and vulnerability make her incredibly grounded. A masterfully executed, high-stakes climax.
Verdict 4.5 / 5 Stars
"A haunting, masterfully executed historical procedural that pairs complex, flawed women with a genuinely chilling small-town conspiracy."
Recs
~Please See Us by Caitlin Mullen (for the author's Edgar Award–winning look at marginalized women and systemic crime)
