"It's been a long time since a book has reached out and just entirely enveloped me in its world the way  Once Was Willem  did. Astounding, and I loved every moment of it." – RJ Barker, author of  The Bone Ships “In  Once Was Willem , M. R. Carey’s gorgeous prose weaves a fable full of dread and wonder, a deeply intelligent and emotionally gripping story boasting one of the nastiest sorcerers you’ll ever meet, and a narrator as inwardly gentle as he is outwardly monstrous. A masterpiece of medieval dark fiction. I love this book. Highest recommendation.”   ― Christopher Buehlman, author of The Blacktongue Thief "Carey crafts an empathetic portrait of a medieval monster as a young man in this revelatory dark fantasy... Wit and compassion, building to a wonderfully satisfying climax. Powerful, captivating, and occasionally stomach-churning, this quintessential tale of good and evil is sure to win fans."  ― Publishers Weekly (Starred Review) "Author Carey demonstrates again that he contains multitudes, jumping from subgenre to subgenre. Also as always, he uses a fantastical setting to consider societal and moral quandaries; in this instance, he explores complex issues of compassion and forgiveness in the wake of (literally) murderous prejudice and intolerance. Despite the story’s high body count, its take on those issues is weirdly optimistic and heartwarming. A dark and hopeful fable with obvious contemporary resonance."  ― Kirkus (Starred Review) "Told through a distinctive narrative voice... An original and expertly written medieval fantasy [that] touches upon the emotional and heartbreaking themes found in Mary Shelley’s Frankenstein." ― Library Journal “An immense achievement, an impeccably crafted book without a single word out of place.”― The New York Times on Infinity Gate "A wild fever dream of a novel – complicated, monstrous, and beautiful."― Seanan McGuire, Hugo Award-winning author "It's been a long time since a book has reached out and just entirely enveloped me in its world the way  Once Was Willem  did. Astounding, and I loved every moment of it – it had me absolutely rapt."― RJ Barker, author of The Bone Ships "It's so absurdly fun and readable, you nearly miss the incredible use of language and lore. Lovable grotesques and ghastly villains populate a compelling folk-tale. Absolutely wonderful."― Gareth Hanrahan, author of The Sword Unbound "A delicious blend of horror, fantasy and historical fiction,  Once Was Willem  gave me exactly what I crave most as a reader - the unexpected. That, and a main character I would fight to the undeath for. A unique and brilliant book"― Jen Williams, British Fantasy Award-winning author of The Ninth Rain "An incredible masterwork of medieval fantasy-horror, dark and twisted and burning bright with humanity.  Once Was Willem  is packed with magic, folklore, superstitious fear, and horrors that bring hope.”  ― Cameron Johnston, author of the Maleficent Seven "A master storyteller." ― io9 on Infinity Gate "M.R. Carey hefts astonishing storytelling power with plainspoken language, heartbreaking choices, and sincerity like an arrow to the heart."  ― Locus on The Book of Koli "A thought-provoking and deeply engaging story ... profoundly and doggedly humane."― C. A. Fletcher on The Book of Koli "Heartfelt, remorseless and painfully human...as fresh as it is terrifying. A jewel."― Joss Whedon on The Girl With All the Gifts "This is a beautiful book. Gripping, engaging, and absolutely worth the time it takes to burrow yourself into its reality. I can't recommend it highly enough."― Seanan McGuire on The Book of Koli "M.R. Carey hefts astonishing storytelling power with plainspoken language, heartbreaking choices, and sincerity like an arrow to the heart."  ― Locus on The Book of Koli "The cadence and pacing of [Koli's] voice adds a depth
