"This is a book for anyone wanting to understand the human brain and personhood; it is a book for anyone with a loved one with dementia and for those of us who fear dementia. In Montague's hands this landscape is rendered more bearable...Montague takes the reader on an exquisite journey into the human brain and beyond that, to the metaphysics of personhood. She does this with a humanity rich in tenderness and a beguiling reverence for the unknown....Occasionally we come across a physicist or economist who, despite their subject matter, can stop you in your tracks. They reel you in without you realising. Montague is a neurologist who does exactly that. She has a rare gift: she makes her craft look simple...Throughout this book Montague displays a maturity and wisdom not always observed in clinicians or indeed any other kind of human."
Irish Times

"A profoundly moving, revelatory book...Like the late Oliver Sacks, Jules Montague writes about bizarre cases...And yet, she is also writing about what it is to be human and the surprising fragility of our sense of self."
