Kylie Boazman reviews the portrayal of autism in How to Fly with Broken Wings by Jane Elson at Disability in Kidlit:
Anyone buying the book will note that the publisher’s description and all of the reviews mention that Willem has Asperger’s, so it’s clear to readers that his standardized traits are meant to represent autism. Willem stims, dumps facts on people at random, counts obsessively, interprets words literally, doesn’t want his food to touch, and reduces facial expressions to “happy face” and “sad face.” Although I always appreciate seeing young characters with anxiety, it’s hard to see Willem as a positive representation of autism for other kids when the author won’t identify him as such.
As in many literary depictions of autism, Willem seems to check off all of the diagnostic boxes without having much of a personality beyond this. Willem isn’t always treated with respect or dignity, particularly when he’s reduced to facts about airplanes and telling people that he can fly. There are also moments that Elson’s writing verges on tropes: in the middle of the book Willem suddenly becomes a magical autistic detective, the likes of which are too often seen in books or on television. He pulls out several pieces of physical evidence and lines of argument to prove that one person wasn’t involved in gang riots, although these abilities are never previously mentioned.
