Heartwood
“The best thriller of 2025.” —The Boston Globe * “Genius.” —The Washington Post
“A literary thriller of the highest order” (Elin Hilderbrand, New York Times bestselling author of The Perfect Couple), Heartwood takes you on a gripping journey as a search and rescue team race against time after a woman mysteriously disappears on the Appalachian Trail.
In the heart of the Maine woods, an experienced Appalachian Trail hiker goes missing. She is forty-two-year-old Valerie Gillis, who has vanished 200 miles from her final destination. Alone in the wilderness, Valerie pours her thoughts into fractured, poetic letters to her mother as she battles the elements and struggles to keep hoping.
At the heart of the investigation is Beverly, the determined Maine State Game Warden tasked with finding Valerie, who leads the search on the ground. Meanwhile, Lena, a seventy-six-year-old birdwatcher in a Connecticut retirement community, becomes an unexpected armchair detective. Roving between these compelling narratives, a puzzle emerges, intensifying the frantic search, as Valerie’s disappearance may not be accidental.
Heartwood is a “gem of a thousand facets—suspenseful, transporting, tender, and ultimately soul-mending,” (Megan Majumdar, New York Times bestselling author of A Burning) that tells the story of a lost hiker’s odyssey and is a moving rendering of each character’s interior journey. The mystery inspires larger questions about the many ways in which we get lost, and how we are found. At its core, Heartwood is an “unputdownable” (Real Simple) and redemptive novel, written with both enormous literary ambition and love.

Don’t be swayed by the zealous reviews. While I found the story compelling and the twist intriguing, the overall narrative felt lacking. At times, I found myself skimming rather than savoring the prose. The characters were relatively uninteresting—unsympathetic, uninspiring, and in some cases, underdeveloped.
The suspension of disbelief required was higher than expected, and the character of Santos felt haltingly and awkwardly integrated into the storyline. What truly unsettled me, however, was learning that a significant portion of the plot closely mirrors a real-life tragedy. I can’t imagine what it would feel like to be the surviving husband or daughter of the nurse hiker who died of exposure on the Appalachian Trail.
This raises ethical questions, and it reinforces a sense that the publishing industry often prioritizes profit over the depth and integrity of storytelling. I would not recommend this book to others—and I certainly wouldn't gift it.
Heartwood runs on a great premise with good pacing. The search-and-rescue plot had me hooked enough to keep going. Beverly Miller, the lieutenant leading the search, is the most compelling presence here: steady, likeable, and the one character I actively rooted for. Lena, meanwhile, feels more like a study in loneliness and neurodivergence than a flesh-and-blood character. Interesting, yes, but she reads more like a symbol than someone you’d actually want to spend a whole chapter with.
Valerie is where it lost me. The novel leans hard on us caring about her “I feel too much, I must escape into the wild” crisis, but the emotional pull isn’t strong enough. Instead of empathizing, I mostly found myself shrugging. If she’s supposed to be the heart of the story, then that heart never fully beats.
In short: strong bones, but a bit hollow in the middle. Worth a read if you like premise-driven novels, but I wouldn’t hike the Appalachian Trail for it.

I went into Heartwood expecting something in the vein of Liz Moore’s The God of the Woods, but it didn’t deliver in the same way. I struggled to stay engaged—the shifting perspectives were often confusing, and I frequently had to reorient myself to figure out whose point of view I was reading. While the premise had promise, the payoff just wasn’t there, and overall, I found the book disappointing.
Following the mystery of a missing hiker on the Appalachian Trail in New England, the author takes the reader on numerous narratives full of back story and personal relationships built from character who are more independent and limited social connections. It was interesting to see how these characters strive on their own and feel about others yet are connected to others on the AT hike. The ending felt a but long winded and torn together but it was still a pleasant read.
This story pulled me in from the first page. Valerie Gillis, a nurse, decides to do the Appalachian Trail. Before she gets to the end, she dissappears in the woods of Maine. Valerie's journal entries, trail partner's interviews, as well as the perspective of the game warden, Lt Beverly Miller, make for interesting reading. It is a page turner.
