'Clever, emotionally resonant, packed with startling twists and dark turns and very funny indeed, this is fiction roaring on all cylinders.' Guardian

'Gloriously dark and tangled . . . clever . . . I highly recommend it.' Observer

'A dark, twisty, savagely humorous plunge into a cauldron of toxic relationships . . . as well as a mystery loaded with menace, this is a smart, layered, stinging look at power and its abuse.' The Times

'Through her bold storytelling, "The Sleepwalkers" becomes a work of peculiar, gonzo genius. ... Thomas takes a glamorous late-capitalist setting, with rosé and catamarans, and shreds, twists and warps it into a story that is surprising, humane and political to its bones.' New York Times

'Thomas tells her story with the craft and cunning of an Aegean sorceress. ... [S]he can make metafiction not just smart but fun. Once more she earns her place in a postwar British canon of playfully serious mavericks that runs from Muriel Spark and Brigid Brophy to Nicola Barker and Ali Smith.' Spectator

'Like a darker, funnier The White Lotus, The Sleepwalkers is horrifying in the best possible way. I loved every moment of it.' James Smythe

'The Sleepwalkers is brilliant, savage and hilarious. The voice is so strong and so distinctive from the get-go, so bold and pitilessly funny. There is no whingeing here, just a fearless takedown which I read through in a single streak of pure delight. This is Scarlett's best yet, and I don't say that lightly.' Bidisha Mamata

'The Sleepwalkers is never-endingly surprising and full of keen observations on relationships, politics, and art. Thomas makes real life so fraught with meaning, it feels hauntingly supernatural. A twisty Gothic tale of vertiginous depths and haunting power.' Sandra Newman, author of Julia

'This original thriller has plenty of surprises.' Good Housekeeping

'An attractive summer holiday read', Independent

'Muriel Spark's disreputable niece.' Spectator

'She's a genius.' Douglas Coupland

'Thomas has the mesmerising power of a great story teller.' Financial Times

'One of the most startling, unpredictable writers of her generation.' Scotsman
