"For more than half a century, there have been no wolves in Yellowstone National Park. Now a howl rings out again: humans have re-introduced two packs to the area. They know the wolves will affect prey species, like the elk that graze the river valley. What they cannot predict is that these magnificent creatures will change an entire ecosystem, improving biodiversity and altering the very landscape."--Back cover.
