Praise for Our Winter Monster A Goodreads Editors’ Pick Kirkus Reviews’s 20 Most Addictive Books of 2025 (So Far) Goodreads Readers’ Most Anticipated Horror Novels of 2025 “Dennis Mahoney continues to build off his explorations into our universal fears of loneliness & inadequacy with a novel firmly set in the horror genre.” —WAMC’s The Roundtable “A wonderful mix of pulpy horror and crime . . . Fast-paced [and] full of chaos . . . Our Winter Monster is just like the blizzard at its core: relentless and constantly violent. There is a lot to like here, but the thing that stands out the most is how the author managed to fill a campy, gory monster tale with complex, engaging, diverse characters.” —Gabino Iglesias, Locus Magazine “Satisfying . . . A hectic, gory, and heartfelt horror story.” —Reactor “Our Winter Monster is a truly satisfying blend of supernatural, survival, and physiological horror. Just as surprising as it is heartbreaking, every page pulls you deeper into a storm that you’ll never forget.” —Erin E. Adams, author of Jackal “Like a couples therapy session straight out of our nightmares, Our Winter Monster serves up a slab of profoundly unsettling relationship terror—probing into the very nature of love by exploring what brings us together and what tears us apart—while ripping the reader to pieces in the process. Dennis Mahoney is just the horror counselor we readers need to see us through this gripping chiller and survive.” —Clay McLeod Chapman, author of What Kind of Mother and Ghost Eaters “Dennis Mahoney’s Our Winter Monster is all the fun of ’80s horror through a modern lens—wild, gleeful horror at its best.” —Sarah Langan, Bram Stoker Award–winning author of Good Neighbors “While Our Winter Monster is a full-tilt horror story, it’s also a moving, nuanced character study of trauma and grief, and what happens when our hearts insist on beating after the worst days of our lives. Mahoney’s a craftsman.” —Keith Rosson, author of Fever House “A fun and frightening descent into the complexities of human connection and the monsters that reveal our innermost worries. Dennis Mahoney’s Our Winter Monster blends a blistering pace with tremendous heart and empathy, the kind that feels like a guiding hand through the darkness. Mahoney’s got the chops; he’s here to scare you shitless while also proving that nobody is ever lost to the frigid temperatures.” —Michael J. Seidlinger, author of Anybody Home? and The Body Harvest “An expertly plotted novel about the difficulties of love and proper communication set against the backdrop of a monster movie. It's just so much fun.” —Underbrush Books, Top New Horror Books of 2025 “Its atmospheric setting, layered characters, and exploration of trauma make [Our Winter Monster] a worthwhile read . . . The snowstorm becomes a character in itself – a silent, omnipresent force that amplifies the isolation and danger the characters face.” —Just Read It Already “A couple on a road trip to fix their marriage instead find themselves stranded in a snowstorm and facing a supernatural threat of epic proportions. [Our Winter Monster] has the same vibes as cult classic I’m Thinking of Ending Things, but with a snowstorm ratcheting the tension way up.” —CrimeReads “At its bitter, frosty heart, Our Winter Monster is an exploration of the human condition. Holly and Brian’s tumultuous relationship is painted with unflinching honesty . . . A compelling read that is icily introspective, quietly horrific in some areas, and unapologetically terrifying in others.” —FanFiAddict “Our Winter Monster merges two classic horror tropes, the small town and the monster of the week, to lay the groundwork for a tale that is at once somber and frightening . . . Mahoney’s narrative spell is empathetic.” —The Lineup “I am a complete sucker for a cold-weather horror novel. Here, a couple heads out on a quick vacation to escape a past mistake—and an incoming blizzard—only to find themselves in the path of a mysterious creature. Let’s just say this ski trip promises more dangers than black diamonds.” —Goodreads Editors’ January Book Picks “A couple grapples with monstrosity in this tense horror novel . . . Mahoney pulls it off beautifully, with legitimately terrifying action scenes and a creeping sense of horror threaded through the book. But where he shines brightest is in his depiction—sensitive and accurate—of post-traumatic stress and anxiety . . . Smart, sensitive, and scary as hell.” —Kirkus Reviews, Starred Review “Ideal for fans of horror like Darcy Coates’s Dead of Winter, this novel is crime fiction blended with horror and psychological suspense. Mahoney has created a work that combines a monster story with the claustrophobia of a massive blizzard while also exploring PTSD and its effects on relationships and individuals.” —Library Journal “Horrific scenes of blood-strewn havoc are eased by plaintive scenes of clarity wherein the balance between being in control, forgetting yourself, and the unstoppable burden of change is cast in a flurrying light. With a broken relationship as its psychological bedrock, the horror novel Our Winter Monster is like a nightmare couple’s therapy session you can’t help but spy on.” —Foreword Reviews “Plenty of in-the-moment tension to hook readers’ interest . . . [and] plenty of blood and guts to keep horror fans happy.” —Publishers Weekly “Will chill you to the bone . . . Not only does [Our Winter Monster] read like a throwback, old-school horror novel — or a beloved B-horror film — it leaves enough to the imagination that readers will be beside themselves with appreciation while they are being properly scared.” —Bookreporter Praise for Dennis Mahoney “With its openly bleeding heart and philosopher’s spirit, the odd and undeniably affecting Ghostlove explores ways in which we haunt ourselves.” ―Paul Tremblay, New York Times Book Review “Quietly powerful . . . Mahoney can share shelf space with Dave Eggers and Stewart O'Nan.” —Booklist, Starred Review “A thoughtful examination on how tragedy can change different people in different ways . . . It also reveals how we often avoid confronting the fear and pain that manifests in our thoughts.” —Zyzzyva “Mahoney crafts sentences that take your breath away.” ―The Times Union (Albany)
