“The Rule of Three is a tense, smart, can’t-put-it-down YA thriller about the collapse of society.” - The National Post
“The book offers wonderful discussions of airplanes and flight, survival, and the importance of community, questions of humanity and human endurance.” - CM Magazine
“All the hallmarks of a good Walters book are here: the teenage perspective is spot on, the male hero rises to the challenges thrown his way, the pace is quick but realistic, danger and adventure are around every corner.“ - Quill & Quire
“The Rule of Three is a fantastic, compelling, unforgettable book! Its simple premise—what if one day all modern technology stopped working—becomes a blisteringly fast tale of survival in a world gone to hell. The genius of the novel isn’t its likeable, reluctant hero, teenage pilot Adam, or its explosive, bullet-ridden, nail-biting action scenes—it’s how believable it is. Walters perfectly captures the fragile nature of civilisation, and how easily that veneer can shatter in times of crisis. The escalation of the plot—the way society implodes as quickly and as violently as a black hole—leaves you breathless. This book makes The Walking Dead look like a walk in the park, because in The Rule of Three the monsters howling outside your gates aren’t the undead but your friends, your fellow students, your coworkers. It will leave you looking over your shoulder to try to work out who would be your friend after the world ends, and who would very quickly become your enemy. Combined with some deft humour, a carefully handled love story, and some white-knuckle plane rides over the growing chaos, The Rule of Three is one of my favourite books of 2014. I just hope there’s a sequel!” - Alexander Gordon Smith, author of The Fury
“Rule of Three maintains a realistic and frightening look at what happens when technology is lost and modern society begins to fall apart.” - School Library Journal
“Adam’s ethical qualms about the ruthless decisions that Herb insists they must make—turning people away from their sanctuary, treating unknown people as threats—make for nuanced reading.” - Booklist
“A solid read that sidesteps most of the SF influence so prevalent in current dystopian fiction.” - Publisher’s Weekly
