RaveOutsideBlakeslee recounts the pack’s rise in gripping detail, from its inauspicious formation in 2010 to its eventual takeover of the prey-rich Lamar Valley, where O-Six’s grandmother once reigned, and its fierce battles with rival packs ... Blakeslee is a gifted storyteller, but the rich particulars of American Wolf were drawn from thousands of pages of observations documented firsthand by the crew of dedicated wolf watchers who have been flocking to Yellowstone National Park since the controversial reintroduction of Canis lupus in 1995 ... That you can’t stop reading despite the looming tragedy is a testament to the genius of Blakeslee’s tautly constructed narrative.
