Knock Knock, Open Wide weaves horror and Celtic myth into a terrifying, heartbreaking supernatural tale of fractured family bonds, the secrets we carry, and the veiled forces that guide Irish life.

Driving home late one night, Etain Larkin finds a corpse on a pitch-black country road deep in the Irish countryside. She takes the corpse to a remote farmhouse. So begins a night of unspeakable horror that will take her to the very brink of sanity.

She will never speak of it again.

Two decades later, Betty Fitzpatrick, newly arrived at college in Dublin, has already fallen in love with the drama society, and the beautiful but troubled Ashling Mallen. As their relationship blossoms, Ashling goes to great lengths to keep Betty away from her family, especially her alcoholic mother, Etain.

As their relationship blossoms, Betty learns her lover’s terrifying family history, and Ashling’s secret obsession. Ashling has become convinced that the horrors inflicted on her family are connected to a seemingly innocent children’s TV show. Everyone in Ireland watched this show in their youth, but Ash soon discovers that no one remembers it quite the same way. And only Ashling seems to remember its star: a small black goat puppet who lives in a box and only comes out if you don’t behave. They say he’s never come out.

Almost never.

When the door between the known and unknown opens, it can never close again.

Neil Sharpson lives in Dublin with his wife and their two children. Having written for theatre since his teens, Neil transitioned to writing novels in 2017, adapting his own play The Caspian Sea into When The Sparrow Falls.

A huge fan of animation, Neil writes Unshaved Mouse, a comedic review blog mostly focusing on animated film and comic book movies.

“Transporting readers to a blood-soaked Ireland, Sharpson (When the Sparrow Falls) delivers modern horror at its best. . . . By turns tender and terrifying, sexy and stomach-turning, heartwarming and heartrending, this folklore-steeped exploration of generational trauma is a high-water mark for the Irish horror novel.”—Publishers Weekly, starred review

“Genuinely terrifying, the sort of book you shut away in the freezer at night so it won’t come looking for you. That is, if you can put it down. Knock Knock, Open Wide deservedly places Neil Sharpson at the front rank of modern horror writers. Open wide, if you dare, and read.”—Alex Grecian, New York Times bestselling author of Red Rabbit

“Irish mythology melds with family damage and a decidedly contemporary love story in this deftly told novel. Circling around one of the most terrifying versions of a child’s TV program in fiction, Knock, Knock, Open Wide has a remarkable ability to reveal the cracks in reality which, if we’re not careful, we can be pushed through, landing in a darker-hued reality that huddles snarling beneath.”—Brian Evenson, author of Song for the Unraveling of the World

“Celtic creepypasta Knock Knock, Open Wide is a dark miracle and Neil Sharpson is an infernal bard belched straight out from Hell itself. Your next nightmare has just arrived.”—Clay McLeod Chapman, author of Ghost Eaters

“Reading Sharpson’s latest. . . is like being grabbed unexpectedly. Readers know something feels terribly wrong but cannot get away from the horror and mystery of the story; it simply demands that they understand the truth and reach its conclusion. Irish folklore provides the foundation for this intriguing, otherworldly book about the doors we keep closed, the doors we cannot help but open, the things we cannot kill, and whether the truth is worth knowing in the end.”—Booklist
