ALEX CARTER SERIES: BOOK ONE

HarperCollins Publishers, October 27, 2020

The first book in a thrilling series featuring a wildlife biologist who courts trouble as she saves endangered species . . . and a mysterious killer who buries his dead in the land she helps preserve—a fast-paced, action-driven tale of suspense with the atmosphere and propulsive tension of works by Jane Harper, C. J. Box, William Kent Krueger, and Nevada Barr.

While studying wolverines on a wildlife sanctuary in Montana, biologist Alex Carter is run off the road and threatened by locals determined to force her off the land.

Undeterred in her mission to help save this threatened species, Alex tracks wolverines on foot and by cameras positioned in remote regions of the preserve. But when she reviews the photos, she discovers disturbing images of an animal of a different kind: a severely injured man seemingly lost and wandering in the wilds.

After searches for the unknown man come up empty, local law enforcement is strangely set on dismissing the case altogether, raising Alex’s suspicions. Then another invasive predator trespasses onto the preserve.

The hunter turns out to be another human—and the prey is the wildlife biologist herself. Alex realizes too late that she has seen too much—she’s stumbled onto a far-reaching illegal operation and now has become the biggest threat. In this wild and dangerous landscape, Alex’s life depends on staying one step ahead—using all she knows about the animal world and what it takes to win the brutal battle for survival.


ALEX CARTER SERIES: BOOK TWO

HarperCollins Publishers, November 9, 2021

Wildlife biologist Alex Carter is back, fighting for endangered species in the Canadian Arctic and battling for her life in this action-packed follow-up to A Solitude of Wolverines, “a true stunner of a thriller debut” (James Rollins) and “a great read” (Nevada Barr).

Fresh off her wolverine study in Montana, wildlife biologist Alex Carter lands a job studying a threatened population of polar bears in the Canadian Arctic. Embedded with a small team of Arctic researchers, she tracks the majestic bears by air, following them over vast, snowy terrain, spending days leaning precariously out of a helicopter with a tranquilizer gun, until she can get down on the ice to examine them up close.

But as her study progresses, and she gathers data on the health of individual bears, things start to go awry. Her helicopter pilot quits unexpectedly, equipment goes missing, and a late-night intruder breaks into her lab and steals the samples she’s collected. She realizes that someone doesn’t want her to complete her study, but Alex is not easily deterred.

Managing to find a replacement pilot, she returns to the icy expanses of Hudson Bay. But the helicopter catches fire in midflight, forcing the team to land on a vast sheet of white far from civilization. Surviving on the frozen landscape is difficult enough, but as armed assailants close in on snowmobiles, Alex must rely on her skills and tenacity to survive this onslaught and carry out her mission.


ALEX CARTER SERIES: BOOK THREE

HarperCollins Publishers, November 15, 2022

Building upon the highly acclaimed debut of Alice Henderson’s A Solitude of Wolverines and its follow-up thriller A Blizzard of Polar Bears comes the eagerly anticipated and electrifying third installment A Ghost of Caribou, in which wildlife biologist Alex Carter encounters an unsolved murder and a town in turmoil while in search of this majestic, all-but-vanished animal. 

When a remote camera on a large, rugged expanse held by the Land Trust for Wildlife Conservation picks up a blurry image of what could be a mountain caribou, they contact Alex Carter to investigate. After all, mountain caribou went extinct in the contiguous U.S. years ago, and if one has wandered down from Canada, it’s monumental.

But when Alex arrives on scene in the Selkirk mountains of northeastern Washington state, she quickly learns that her only challenge isn’t finding an elusive caribou on a massive piece of land. The nearby townspeople are agitated; loggers and activists clash over a swath of old growth forest marked for clearcutting. The murdered body of a forest ranger is found strung up in the town’s park, and Alex learns of a backcountry hiker who went missing in the same area the year before.

As she ventures into the forest in search of the endangered animal, she quickly finds herself in a fight for her life, caught between factions warring for the future of the forest and a murderer stalking the dense groves of ancient trees.

When wildlife biologist Alex Carter is tasked with locating jaguars on a vast desert preserve in New Mexico, she is ecstatic. While jaguars once roamed throughout the Southwest, they are now endangered, with only a handful remaining, and Alex hopes some of the sleek and elusive creatures have found their way to the protected sanctuary.

Meanwhile, an archaeological team is excavating the gravesite of a sixteenth-century Spanish conquistador on a neighboring piece of land. Curious about the dig, Alex meets the team and, while learning about their discoveries, she encounters a dangerous group of anti-immigrant vigilantes roaming the area, threatening the archaeology team, demanding they leave. And when the militants learn of Alex’s mission, they become bent on stopping her. Because jaguars are federally endangered, the vigilantes worry that if Alex finds them, concessions will be made so that wildlife can cross the border wall. And they want no one crossing it…

And then there are the strange holes that keep appearing on the preserve—Who is digging them, and what are they looking for? As tensions mount, Alex soon finds herself in a fight for her life against those who would prevent her from restoring jaguars to their historical habitat.


PRAISE FOR THE ALEX CARTER NOVELS

A true stunner of a thriller debut. Both a mystery and a survival story, here is a novel written with a naturalist’s eye for detail and an unrelenting pace. It reminded me of the best of Nevada Barr, where the wilderness itself is as much a character as the feisty wildlife biologist who must solve a crime in a remote town where no one is talking, and everyone is a suspect. It’s so fraught with excitement and wondrous details that it demands to be read in one sitting and savored afterward. Don’t miss it.” (—James Rollins, #1 New York Times bestselling author of The Last Odyssey )
