Five years after "Findings" broke the mould of nature writing, Sort of Books presents "Sightlines". The outer world flew open like a door, and I wondered - what is it that we're just not seeing? In this greatly anticipated sequel to "Findings", prize-winning poet and renowned nature writer Kathleen Jamie takes a fresh look at her native Scottish landscapes, before sailing north into iceberg-strewn seas. Her gaze swoops vertiginously too; from a countryside of cells beneath a hospital microscope, to killer whales rounding a headland, to the constellations of satellites that belie our sense of the remote. Written with her hallmark precision and delicacy, and marked by moments in her own life, Sightlines offers a rare invitation to pause and to pay heed to our surroundings.
