*An up-all-night slice of Halloween horror, perfect for fans of Stephen King, Black Mirror, and Frankenstein*

'A gauntlet of thrills and surprises . . . If reading with one hand over your mouth is your thing, this is the book for you' Gus Moreno, author of This Thing Between Us

Henry, a brilliant but reclusive engineer, has achieved the crowning discovery of his career: he's created an artificially intelligent consciousness. He names the half-formed robot William.

But there's something strange about William.

It's not that his skin feels like balloon rubber and is the colour of curdled milk, nor is it his thick gurgling laugh or the way his tongue curls towards his crooked top teeth. It is the way he looks at Henry's wife, Lily.

Henry created William but he is starting to lose control of him. As William's fixation with Lily grows and threatens to bring harm to their house, Henry has no choice but to destroy William.

But William isn't gone. Filled with jealousy for humanity, for its capacity to love and create life, William starts to haunt the house.

He lurks behind each locked door. You can hear him muttering in the eaves of the attic. He is whispering in Henry's head. And he will be the one to take control . . .

William is a new kind of ghost story, where the haunting is not from another world, but from inside your home. Inside your head . . .

'From its first page all the way to its jaw-dropping ending, William had me hooked' Nick Cutter, author of The Troop and The Deep

'A gripping page-turner that makes you think' Araminta Hall, author of One of the Good Guys

Reviews
Coile locks you in the smart home of your nightmares, and inside is a gauntlet of thrills and surprises that'll have you looking over your shoulder till the very end. If reading with one hand over your mouth is your thing, this is the book for you -- Gus Moreno, author of THIS THING BETWEEN US
From its first page all the way to its jaw-dropping ending, William had me hooked. I mainlined this book in one sitting, loving the tragically endearing protagonist Coile had created while marvelling at the whip-smart plotting -- Nick Cutter, author of THE TROOP AND THE DEEP
Mason Coile's William is twisted, timely, scarily intelligent, and menacing even before it reveals its greatest, darkest secrets -- Jonny Compton, author of THE SPITE HOUSE
A gripping page-turner that makes you think, William gets you by the throat and doesn't let go until it has spun you through some of your darkest fears. Mason Coile has written a modern-day Frankenstein for our digital age that grapples with the notion of consciousness and what makes a human -- Araminta Hall, author of ONE OF THE GOOD GUYS
Praise for the author--

One of the most talented successors to Stephen King

One of the most exciting works of fiction I've read for some time

-- Kate Mosse, author of THE GHOST SHIP on THE DEMONOLOGIST
Genuinely terrifying, don't-read-late-at-night stuff. Thrilling, compelling and beautifully written -- SJ Watson, bestselling author of BEFORE I GO TO SLEEP on THE HOMECOMING

Richly crafted, deliriously scary and compulsively page-turning from beginning to end

-- Jeffrey Deaver, author of THE BONE COLLECTOR on THE DEMONOLOGIST
