The most intriguing horror novel of the year so far... Reads like Shirley Jackson or Catriona Ward at their most gothically playful. It's a wholly unique intellectual exercise and a deeply compelling page-turner - Esquire

An original take on the secrets that houses keep, with every page drenched in foreboding. The Underhistory has all the hallmarks of a contemporary gothic classic -- Erin Kelly, author of HE SAID/SHE SAID

A heartfelt and chilling gothic tragedy. Unbearably creepy, original and devastating -- Chris Whitaker, author of WE BEGIN AT THE END

An inventive, layered haunted house novel, where ghosts reside amid the dust and each room holds its own message for the unwary visitor. Kaaron Warren is one of a kind -- Alison Littlewood, author of A COLD SEASON

What an absolutely brilliant book this is! Superbly written, completely unique. Haunting, smart, and provoking -- L.V. Matthews, author of THE TWINS

A unique jewel box of a book - tense locked room thriller meets haunted house gothic, pulled off with immense skill -- Lizzy Barber, author of OUT OF HER DEPTH

Eerie, menacing, and totally original -- Philippa East, author of LITTLE WHITE LIES

A fascinating and unnerving character study of a house and its sole survivor. A sinister, tense, and satisfying read, I absolutely loved it -- Carole Johnstone, author of MIRRORLAND

Strange, sinister and marvellously written. A box of Gothic delights -- Anna Mazzola, author of THE CLOCKWORK GIRL

A vivid gallery of melancholy, joy, and horror. This book is infused with a love of places and objects, the stories they carry, and the stories they inspire. A vibrant heroine, loathsome villains, and a compelling setting make The Underhistory a haunting treasure, written by a master of her craft -- Daniel O'Malley, author of THE ROOK

Hauntingly creepy, this twisty, layered thriller will upend your expectations and spin you deep into a house of dark secrets. I utterly lost track of right and wrong, and was gunning all the way for my new favourite heroine -- Rachael Blok, author of THE SCORCHED EARTH

Warren wraps the reader in a fabric embroidered with tragedy and story, loss and memory. She enchants us with whimsy and lures us with hope, anchoring the past to the present with ordinary objects. The Underhistory is a triumph, intricately woven and mesmerisingly told -- Sulari Gentill, author of PAVING THE NEW ROAD

Suspenseful, evocative, dark and original. Highly recommended -- Diane Jeffrey, author of THE SILENT FRIEND

A wonderfully weird and creepy journey through a haunted house, peppered with moments of proper darkness -- Tariq Ashkanani, author of WELCOME TO COOPER

Hauntingly dark and beautifully written, The Underhistory keeps you on edge throughout. There are moments of humour interspersed with tragedy and fear. A brilliant read with a wonderful protagonist -- Guy Morpuss, author of FIVE MINDS

Sinuous, slippery, and wrong foots you at every turn. I've never read anything like it -- Tim Glister, author of A LOYAL TRAITOR

Unusual, clever, poetic, haunting and utterly thrilling -- Louise Swanson, author of END OF STORY

Totally unique, I haven't read anything like this for a long time, not since the heady days of Iain Banks' unpredictably dark novels. The sinister suspense that builds up as elderly Pera takes us on a tour of her ghostly family home is masterful. This book will stay with me for a long time -- Jo Furniss, author of DEAD MILE

An elegant, Gothic delight with an eerie seam running through every page. Read on a dark, cold night if you dare -- Victoria Dowd, author of THE SUPPER CLUB MURDERS

A dark and magnificently inventive upmarket thriller about the lengths a lone woman will go to protect her home, and the family history it hides within its walls.
