Haupt, Science “Quietly prophetic. ” - Jedediah Purdy, Atlantic “Profound in every sense of the word.” - Richard Powers “Underland is a devastating act of witness and a clear, cogent, lyrical examination of the darknesses invisible beneath our feet.” - Lauren Groff “Underland is a profound reckoning with humankind’s self-imperiled position in nature’s eternal order. At once thrilling and soulful, raw and erudite, it is a book of revelations.” - Philip Gourevitch
