Helen Macdonald's bestseller H Is for Hawk told the story of a grieving daughter who found healing in training a goshawk. The goshawk is one of Mother Nature's own fighter jets, capable of finding and killing its prey with the speed of a lightning bolt. Now Macdonald digs deeper into the world of these raptors by following a family in the wild while raising and training a new goshawk of her own.
