Knife River

by Justine Champine

“A twisting, engrossing, and beautiful mystery. Thrilling, yet also deeply moving, layered, and powerful.”—Chris Whitaker, New York Times bestselling author of All the Colors of the Dark, a Read with Jenna Book Club pick as seen on Today

“A delicious smoke curl of a novel.”—#1 New York Times bestselling author Jodi Picoult

“An intelligent literary mystery.”—#1 New York Times bestselling author Paula Hawkins

A compelling story of family, home, and the bond between sisters that asks: Who do you believe when you can't even trust yourself?


When Jess was thirteen, her mother went for a walk and never returned. Jess and her older sister, Liz, never found out what happened. Instead, they did what they hoped their mother had done: survive. As soon as she was old enough, Jess fled their small town of Knife River, wandering from girlfriend to girlfriend like a ghost in her own life, aimless in her attempts to outrun grief and confusion. But one morning, fifteen years after their mother’s disappearance, she gets the call she’s been bracing for: Her mother’s remains have been found.

Jess returns to find Knife River—and her sister—frozen in time. The town is as claustrophobic and rundown as ever. Liz still lives in their childhood home and has become obsessed with unsolved missing persons cases. Jess plans to stay only until they get some answers, but their mother’s bones, exposed to the elements for so long, just leave them with more questions. As Jess gets caught up in the case and falls back into an entanglement with her high school girlfriend, her understanding of the past, of Liz, of their mother, and of herself become more complicated—and the list of theories more ominous.

Knife River is a tense, intimate, and heartrending portrayal of how deeply and imperfectly women love one another: in romantic relationships, in friendships, and especially as sisters.

The main storyline of Knife River follows Jess. Jess was thirteen when her mother disappeared. Her mother’s disappearance and her older sister raising her had a drastic impact on Jess. She drifted from one relationship to another and kept everyone (including family) at arm’s length. One day, she receives a phone call from her older sister that turns her world upside down. Her mother’s body had been found, and she needed a home. Jess is determined to understand why her mother disappeared and looks for answers. The deeper she digs, the more she uncovers about her mother; not all is good. The answers she seeks might be different from what she wants to hear.

Knife River is a slow book. The slowness grated on me in places, but I understood why the author chose to keep it at this pace. The book needed to be slow to understand Jess’s state of mind and her actions throughout the book.

Jess was not likable, but I couldn’t help but feel bad for her. Sometimes, she couldn’t get out of her own way and made things worse for herself. She also did and said things that made my eyebrows raise and made me wonder, “Why?” She was so damaged, and the author didn’t sugarcoat it.

The mystery of Jess’s mother’s disappearance was very well written. The author did a great job of showing what went into investigating a cold case and trying to find leads after fifteen years. She showed Jess and her sister’s frustration with the police when they stopped communicating with them about the case (of course, there was another reason why). I also liked Jess’s investigation and how she accidentally stumbled upon the truth of what happened. That was a massive twist to the disappearance. It was one that I didn’t see coming and took me completely by surprise.

The end of Knife River left me with more questions than answers. I was confused as to what happened with Jess and the girl she was sleeping with and why she just sat on the confession she got. But I did like that Jess and her sister had grown closer at the end of the book and, in a way, started healing from their mother’s disappearance.
