"Atlas of Unknowable Things is smart. Extremely smart, carefully plotted and well-researched. And while this horror novel share DNA with Dan Brown-esque conspiracy thrillers, author McCormick Templeman is better. Much better." - BookPage "Smart, twisty, and delightfully creepy." - Jay Kristoff, New York Times bestselling author "A dazzling novel of illusion, clever and eerie, whipsmart in its execution. I devoured this puzzle-box of a novel and will read whatever McCormick Templeman writes next." -Brittany Cavallaro, New York Times bestselling author of A Study in Charlotte "Atlas of Unknowable Things is one of those rare novels with the power to adjust your grip on reality.

Reading it feels like being in an escape room with a (not-racist) Lovecraft while sipping cocktails made of rare and marvelous herbs." -- Camille DeAngelis, Alex Award-winning author of Bones & All " Atlas of Unknowable Things sent me down a dark, twisting rabbit hole while the author secretly reoriented my brain chemistry to only desire more of this book. When I wasn't reading it, I was thinking about it--Wildly addictive, terrifying, and smart as hell." -- Sadie Hartmann, Bram Stoker Awards® winning author of 101 Horror Books to Read Before You're Murdered " Atlas of Unknowable Things is suspenseful, smart, and spooky. Templeman combines a vivid style that you'll want to take the time to savor with a such tight, twisty narrative that you'll end up racing through the pages anyway. This is one you'll want to read more than once!" - C. J. Dotson, author of The Cut.
