PRAISE FOR JASON REKULALK
I loved it. The surprises really surprise and it has that hard-to-achieve propulsiveness that won't let you put it down. And the pictures are terrific! -- STEPHEN KING
Must be the boldest double twist of the year. Truly fantastic * THE TIMES *
Tightly plotted and well written [...] A gripping page-turner with intriguing characters and genuinely creepy moments * DAILY MIRROR *
Hidden Pictures isn't a ghost story, it's a scalpel that slices into our smug sense of self-satisfaction so deeply it hits bone. A perfect summer thriller complete with vengeful spirits, class warfare, and it even has pictures. What more could you want? -- GRADY HENDRIX
Whip-smart, creepy as hell, and masterfully plotted, Hidden Pictures is the best new thriller I've read in years. Destined to be a classic of the genre -- RANSOM RIGGS
