A Blizzard of Polar Bears

Alex Carter is just winding down a research project in Montana—she’s a wildlife biologist—when a fellow scientist calls to see if she would like to lead a study of polar bears. Within weeks she’s at a scientific research center in Churchill, Manitoba, polar bear capital of the world. Accompanied by a research assistant and a pilot, Carter flies over the frozen terrain of Hudson Bay in a helicopter, seeking bears. When she locates one, she shoots it with a tranquilizer from the helicopter then descends to quickly tag it and take samples. Henderson does a terrific job in describing life in Churchill, especially the effort to survive in such a hostile environment, but even more compelling is the information about the polar bears, struggling to live despite climate change, loss of prey, and increased exposure to toxins. Slowly Alex’s study is undermined—someone breaks into the lab and steals her samples, her supplies are tampered with, her pilot disappears—until on one mission the plane itself sets on fire, leaving Alex and her team stranded on the ice, miles from anywhere. Henderson manages to marry both suspense and mystery in this book, featuring a classic, suspense-driven fight-and-flight with several overarching mysteries. It’s even better than the excellent first book in the series, A Solitude of Wolverines. Fans of Nevada Barr’s Anna Pigeon novels may well enjoy this.
