Exhilarating ... dazzling ... a miraculous feat

A mental-health memoir like no other … a genre-defying wake-up call of a book … compelling … clever humane … holding back a sly twist for the end

Let Me Not be Mad is stunning: clever, troubling, restless, honest, dishonest; one of the best portraits of madness and clinical practice I’ve read. I read it in two sittings. Extraordinary

A perfectly extraordinary – not to mention extraordinarily perfect – tense Hitchcockian psychodrama. I have rarely read a more haunting and enthralling account of a descent into madness. An important, profound and fascinating book

Imagine a gonzo Oliver Sacks communing with Edward St Aubyn’s Patrick Melrose, R.D. Laing and the spirit of Kafka’s 'The Country Doctor', and you still won’t quite have the flavour of this wild and strikingly original book

Brilliant and alarming, written with cunning and self-lacerating honesty. The doctor is sick, but his intelligence, his scope of reference, his damaged sagacity could save us all

Blackly comic, warmly compassionate, a unique take on the human mind offering uncomfortable universal truths

A treasure of a book. Intricately woven and deeply intimate, it reveals things that astonish, surprise and improve us

A truly astonishing journey into and out of the mind. Not content to pin you down with the intense intimacy of his storytelling Benjamin dramatises some of the most profound and intractable issues in neuroscience and psychiatry. I’ve never read anything like it

Like a meeting of Oliver Sacks and Hunter S Thompson … this is not a simple narrative of striking cases written by a far-seeing practitioner. It’s a turbo-charged race

At first I thought this an exceptionally well written book in the genre of medical story telling. The more I read the more I realised it’s an exceptional book in a genre all of its own. Insightful, wonderfully well observed and beautifully written

A slow-burn belter of a book ... terrific ... so finely described, the result has the terse force of a classic short story

Strange, claustrophobic, haunting … a dizzying whirlpool

Brilliant and engrossing

Along the way the anonymised author, AK Benjamin, offers funny and unsettling insights into the vagaries of the relationship between clinicians and patients

A creative account of a life with little sleep… Readers looking for their own cure will instead find an erudite companion to help them through the dark times.

It's funny, sad, wry, always worrying away at the mystery of sleep and its absence and finding endless new angles so that the whole has something of the quality of those waking dreams that haunt the insomniac and are her private country.

A slim, intense memoir about her own year-long experience of nocturnal unrest… a torture Harvey describes with a combination of desperation, wry humour and — despite the scarcity she is subjected to — a deeply felt sense of life’s abundance… [her] prose…glows off the page: an exacting inquisition of the self leading to imperfect peace.

[Harvey is] brilliant on words and the nature of writing.

[With The Shapeless Unease] Harvey has certainly proved that insomnia, as much as any of the more obviously nasty diseases, might be as worthy a subject of literature as love, battle or jealousy…her book rises to that level.

[A] bravely exposing deep dive into the emotional murk of her [Havey’s] restless mind….[it] reveals…the irresistible writerly impulse to pin experience to the page.

[The Shapeless Unease] reads like a dream sequence… Even reading this made me feel dizzy… [Harvey is] a vigorous, eloquent writer… she conveys the way sleeplessness takes you into the death zone of life.

Mesmerising…at times, bitingly funny… [The Shapeless Unease is] an engrossing portrait of the fragility of identity and coherency in the grip of insomnia. I hadn’t read Harvey before this, but her facility with language here captivated me and I’ll be seeking out her novels next.

Urgent and full of arresting images and insights.

[The Shapeless Unease] is littered with sharp insights expressed in exquisitely lucid prose but is as amorphous as its title suggests.

It’s a claustrophobic, enlightening, moving, existential treatise on sleep, insomnia and death. And it’s funny, too.

I wish I had saved The Shapeless Unease to read in isolation but Samantha Harvey’s book about insomnia, time, death and so many unknowable things is a blessing to have in lonely times. It is a profound and stunning book but funny, too.

A beautiful, jagged little book about insomnia and so many unknowable things: life and death, Buddhism, and how language alters our thinking. But I was most struck by its form and structure.

[Samantha Harvey's] cerebral, startlingly clear account of somehow pulling through [from insomnia] carries an electric charge and meditates on not only the mystery of sleep but also writing, swimming and dreams.

[The Shapeless Unease] is beautifully crafted and its achievement makes itself more apparent on a second reading.

A masterpiece, so good I can hardly breathe. I'm completely floored by it.

This book seems appropriately messy-haired and wild-eyed... Anyone who has lain awake the night before a big test will recognize such manic flourishes. Harvey captures the 4 a.m. bloom of magical thinking; stories proliferate within stories... To read Harvey is to grow spoiled on gorgeous phrases.
