UK praise 

"[Marsden's] enthusiasm for the subject is contagious, and he writes with a rock-collector's eye for glittering details. One senses this is a book he has been longing to write for years" ―The Guardian

"A luminously rich exploration of the mineral wonderland beneath our feet. Imaginatively travelled and beautiful written" ––Colin Thubron

"A book of breathtaking wealth and depth, as passionate as it is clear-eyed (and funny). Marsden takes the history of metals and, from it, creates a dazzling history of humanity and our relationship with this planet. It can only be alchemy" ––Tom Bullough

"Glorious... a nuanced work... This is a scholarly work rich in history, science and ecology... [Marsden] has a gift for fusing the technical facts with his personal travel narrative" ––Country Life

"Philip Marsden's new book is a wunderkammer, and well worth reading ... The charm and the genius of this book is in its ability not to pigeonhole itself" ―Daily Telegraph

"Mind-boggling... deeply thoughtful, well-written and illuminating journey through the world of minerals and an exploration of their impact on the life and history of our planet" ―Literary Review

"A love letter to these key resources hidden within rocks and buried beneath the earth...Under a Metal Sky is a gracefully meticulous book, full of lyrical nature writing and didactic memoir. Accompanied by a lively cast of characters—from heavy-metal obsessed miners in Austria to the copper-loving poet William Blake—Marsden takes the reader on a tour of our metallic history" ―New Statesman

"Absorbing...It is a vast subject, and Marsden has a prospector's eye for finding glitter" ―The Times Literary Supplement

"Under a Metal Sky takes the reader through a strange and mystical history of metals that is as dark as it is dazzling... As compelling and sometimes fantastical as a novel... A timely reminder of the dangers of an economy of extraction, detailed in a similarly dreamlike prose to Robert McFarlane and WG Sebald" ―Irish Times

"[A] lyrical meditation on the riches beneath our feet, from ochre and mercury to gold and lithium. . . Like his earlier works—The Crossing Place, The Spirit-Wrestlers and Rising Ground—that trace journeys through Armenia, Russia and Cornwall respectively, the writer and historian explores the ties between landscape and who we are. The narrative blends travel writing with philosophical inquiry, starting and finishing in his home region...Marsden’s sense of awe is palpable."—Anjli Raval, The Financial Times
