“A sumptuously written, chilling folk horror novel.”—Paul Tremblay, New York Times bestselling author of Horror Movie and A Head Full of Ghosts

One of Publishers Weekly’s Most Anticipated Books of the Year

Carwyn and his wife, Rhian, have lived a quiet life as sheep farmers in the remote Welsh mountains for decades, tending to ancestral land that has been in Carwyn’s family for generations. But recent years have taken their toll: local friends lost one by one to old age or rising prices; the accumulation of debts; new English tourists, more every year, disrespecting the land—littering, camping on private property, needing to be rescued when they misjudge the elements.

When Carwyn finds a strange stone head in a disused corner of the farm, he realizes the artifact is just one piece of something much larger—something unfathomably old. Despite Rhian’s protests, Carwyn becomes obsessed with unearthing the structure, and soon neglects the daily work of the farm to keep digging. Meanwhile, the sheep fall sick more easily than any season before, and a tragic accident on market day threatens to leave an increasingly isolated Rhian without a way to satisfy their ever-more-insistent creditors. Through it all, Carwyn becomes convinced that uncovering the site and determining its original purpose will be the key to solving everything. But there was a reason his ancestors kept the past buried, and in disturbing the earth, he has called forth a power greater and more terrible than he could have imagined.

Enthralling and atmospheric, Liam Higginson’s The Hill in the Dark Grove expertly weaves together myth, psychological suspense, and supernatural horror, heralding a sparkling new literary talent.
