In an exquisitely chilling debut novel, four children unravel the mystery of a family curse — and a ghostly creature known in folklore as Long Lankin.

When Cora and her younger sister, Mimi, are sent to stay with their elderly aunt in the isolated village of Byers Guerdon, they receive a less-than-warm welcome. Auntie Ida is eccentric and rigid, and the girls are desperate to go back to London. But what they don’t know is that their aunt’s life was devastated the last time two young sisters were at Guerdon Hall, and she is determined to protect her nieces from an evil that has lain hidden for years. Along with Roger and Peter, two village boys, Cora must uncover the horrifying truth that has held Bryers Guerdon in its dark grip for centuries — before it’s too late for little Mimi. Riveting and intensely atmospheric, this stunning debut will hold readers in its spell long after the last page is turned.
