Animals don't exist to teach us things, but that is what they have always done, and most of what they teach us is what we think we know about ourselves.From the bestselling author of H is for Hawk comes Vesper Flights, a transcendent collection of essays about the human relationship to the natural world. Helen Macdonald brings together a collection of her best-loved writing along with new pieces covering a thrilling range of subjects. There are essays here on headaches, on catching swans, on hunting mushrooms, on twentieth-century spies, on numinous experiences and high-rise buildings; on nests and wild pigs and the tribulations of farming ostriches.
