Praise for Colin Gets Promoted and Dooms the World

"The humor throughout this novel is delightfully witty in a way that fans of dry satire will greatly enjoy. Filled with top-notch worldbuilding, entertaining antagonists, and tongue-in-cheek charm . . . this novel is not to be missed for fans of urban fantasy that gently toes the horror line. A charming corporate horror novel with a whole lot of heart."
—Kirkus (starred review)

“Fun. . . . Waddell’s novel carefully balances humor and horror with broken dreams and gray morality. . . . Most readers won’t have experienced as much workplace death, dismemberment, or eldritch horror as Colin, but this underdog revenge fantasy is for anyone who has been bullied, ignored, or taken advantage of.”
—Library Journal

“This book is anything but another day at the office. Charmingly twisted and twistedly charming, Colin Gets Promoted and Dooms the World is as timely and poignant as it is witty and imaginative."
—Maxie Dara, author of A Grim Reaper's Guide to Catching a Killer

“Sure, the problem of evil is a complex, multi-faceted, devastating, and challenging subject; but what about evil that is hilarious?. . . . The consequences of Colin's ambitions may be dire, and every joke is delivered at knifepoint, but that doesn't make you laugh any less. If you want your moral centre to be gleefully eroded by indefensible characters, selfish love, and literally cutthroat office politics, this is the vice for you.”
—Natalie Zina Walschots, author of Hench

“Mark Waddell’s Colin Gets Promoted and Dooms the World is . . . full of office politics, and high stakes. . . . Fans of office comedies will love this snarky and satirical story.”
—She Does the City

“Waddell delivers the perfect balance of humor, chaos, and horror into a terrific page-turning narrative.”
—Criminal Element

"With plenty of jokes about shady executives, corporate drudgery, and ritual sacrifice, Waddell has created a romp that will have readers wondering how Colin will get himself and the world out of the mess he's created...hilarious contemporary fantasy."
—Shelf Awareness

“The blend of corporate satire with eldritch horror made for a sharp, entertaining fusion that felt both absurd and uncomfortably fitting.”
—Game Vortex

"Waddell's writing is sharp, with strong pacing and a good line-by-line balance of horror and comedy."
—Library Journal (starred review)

“Amusing and gruesome, Mark Waddell’s mile-a-minute plot keeps the pages turning in this novel of a mild-mannered nobody looking for a path to genuine power. . . . Delightfully macabre and funnily zany.”
