[ 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 * 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...

Marsden's sense of awe is palpable... he sees geology as a metaphor for civilisation, the earth's layers echoing those of human memory * FT * 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 *
