A collection of tales from the far frontiers of psychedelic experience . . . superb . . . brilliant -- Charles Foster * TLS * Canny and somewhat sceptical ... rigorous and penetrating ... illuminating ... this is a wonderful book, a journey into the nature and potential of consciousness itself, and of life on this troubled and monopolised planet * Literary Review * Philosophical and darkly humorous ... for all the mystical experiences [ psychedelics] afford, divesting them of their shadow side does seekers a disservice, Mitchell holds * Spectator * A powerful reminder that psychedelics cant be made sense of entirely within a framework of chemical interactions in the brain. We need to view them as something potent, to be respected * New Scientist * An incisive, deeply personal and beautifully written account of the power, the uses and the modern misuses of psychedelics. Highly recommended -- Anil Seth, author of Being You An original and thrilling investigation into psychedelics and the claims that currently surround them, achieving profound insights into their essential qualities -- Mike Jay, author of Psychonauts Utterly compelling. Some books are in a category of their own and this is one them. Reading it is like having an out of body experience -- Mark Miodownik, author of Stuff Matters Beguiling, captivating, mind-expanding. It's impossible to read this book and not be tempted to replicate some of its wild, sanity-stretching forays into the peculiarities of human perception -- Stuart Ritchie, author of Science Fictions A dazzling, timely book, as deep and poignant as it is madcap and hilarious -- Professor Mark Lythgoe, Director of the Centre for Advanced Biomedical Imaging, University College London A hair-raising hurtle of a ride into the belly of the psychedelic renaissance, fuelled by spectacular prose -- Henry Shukman, author of One Blade of Grass
