The writer Rebecca Gransden posted an incisive review of A Set of Lines on Goodreads. Excerpt below:

There is a shorthand inherent in tackling dystopian themes, and Stewart moulds a knowing backdrop, using that shorthand to create a scaffolding which amplifies the atmosphere of benumbed melancholy. Throughout, there is an overwhelming sense of longing underneath the surface, a longing obfuscated and perhaps suppressed for so long, that its very function is being forgotten. The unconscious mind and its rebellion against passivity in the face of the denial of human wants and dignities is very present in this novel.
