Book excerpt: “A redemption story, an adventure story, and perhaps above all, a love story.”—Nate Blakeslee, New York Times-bestselling author of American Wolf The Druid Peak Pack was the most famous wolf pack in Yellowstone National Park, and maybe even in the world. This is the dramatic true story of its remarkable leader, Wolf 21—whose compassion and loyalty challenges commonly held beliefs about alpha males. In this compelling follow-up to the national bestseller The Rise of Wolf 8, Rick McIntyre profiles one of Yellowstone’s most revered alpha males, Wolf 21. Leader of the Druid Peak Pack, Wolf 21 was known for his unwavering bravery, his unusual benevolence (unlike other alphas, he never killed defeated rival males), and his fierce commitment to his mate, the formidable Wolf 42. Wolf 21 and Wolf 42 were attracted to each other the moment they met—but Wolf 42’s jealous sister interfered viciously in their relationship. After an explosive insurrection within the pack, the two wolves came together at last as leaders of the Druid Peak Pack, which dominated the park for more than 10 years. McIntyre recounts the pack’s fascinating saga with compassion and a keen eye for detail, drawing on his many years of experience observing Yellowstone wolves in the wild. His outstanding work of science writing offers unparalleled insight into wolf behavior and Yellowstone’s famed wolf reintroduction project. It also offers a love story for the ages. “Like Thomas McNamee, David Mech, Barry Lopez, and other literary naturalists with an interest in wolf behavior, McIntyre writes with both elegance and flair, making complex biology and ethology a pleasure to read. Fans of wild wolves will eat this one up.”—Kirkus starred review
