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.

1994. In the myth-riddled 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.

Woman with long brown hair in a white blouse stands by a wooden fence with green ivy, outdoors.
Caitlin Mullen is the author of Please See Us, which won the 2021 Edgar Award for Best First Novel and was named a New York Times Best Crime Novel in 2020. She lives in New Jersey with her husband and children.

“A beautiful and propulsive literary mystery perfect for fans of Tana French and Liz Moore—Heather is a deeply immersive, eerie, and timely novel about girlhood, motherhood, and friendship; the stories we inherit and the ones we create; and who deserves punishment for the most intimate crimes. Caitlin Mullen is an extraordinary chronicler of women’s grit and resilience–and the unfathomable choices we make when our backs are against the wall. I loved this novel.”

Amy Tintera
author of New York Times bestseller Listen for the Lie

“Visceral as a wound and nuanced as a river’s crosscurrents, Mullen’s latest is a tour de force exploration of the intersection between generational trauma and generational corruption, a story brimming with equal parts horror and humanity. With HEATHER, Caitlin Mullen is at the height of her powers.”
