Part memoir, part medical cautionary tale, Dumb tells the story of how the author copes with the everyday challenges that come with voicelessness. Webber adroitly uses the comics medium to convey the hurdles she faced as well as the fear and dread that accompanied her journey to regain her life. She learns to lean on the support of her close friends, finds self-expression in creating comics, and comes to understand and appreciate how deeply her voice and identity are intertwined.
