A young female wolf, brought from Canada and released in Yellowstone National Park, explores the snowy land. Seeing no other wolf tracks, she roams alone, unsuccessfully hunting elk. She howls, but as she has no pack, no one answers. As the seasons change, she matures, and her hunting skills improve. She finds a mate and gives birth to a litter of four pups. After they emerge from the den and eat the meat brought by the male, the wolves howl together as a family pack. Based on actual wolves released in Yellowstone in 1995, the story personalizes the project, which restored the wolf population in the region. Markle's matter-of-fact tone creates empathy without anthropomorphism, while the use of present tense brings a sense of immediacy to the narrative.
