It is the Winter Solstice and Sarah Sands is sitting by her father's bedside, bracing herself for loss. What her father needs to do, she thinks, is conserve his energy - to hibernate like a hedgehog. When the hedgehog curls up in its bed of leaves, its heart rate slows, its body temperature drops and for months there it remains, hardly breathing at all. A few days earlier, Sarah and her grandson had found a poorly hedgehog in the garden and taken it to the local hedgehog sanctuary. They named her Peggy, and her fate had become a matter of pressing concern. When death looms, it's easier to talk about hedgehogs. There is something about these homely and yet mysterious creatures - prickly and defenceless, wild and tame - that, as Ted Hughes put it, makes us feel deeply sympathetic towards them. "The hedgehog was around long before the human species: it existed 56 million years ago. It tells us a great deal about British civilisation...” Rory Stewart Hedgehogs have captured the imagination of poets and philosophers for centuries. They have managed to outlive roads, dogs, strimmers and pesticides, but now they are an endangered species. For Sarah Sands, our failure to protect them is a symptom of our alienation from the living world. But all is not yet lost. In this charming, idiosyncratic book, she explores the meaning and morals of hedgehogs, and finds, in hedgehog world, a source of deep solace and wisdom.
