Darkwing (known as Dusk in the United Kingdom) is a 2007 young adult fantasy novel by Canadian author Kenneth Oppel.

[3] Booklist's Michael Cart called the novel "richly plotted" and "fast-paced" and highlighted how "Oppel writes with keen insight and empathy about the condition of being other".

Eric Norton, writing on behalf of School Library Journal, also pointed out Oppel's "celebration of difference".

[2] Kirkus Reviews highlighted the novel's "rich sensory details [that] bring to life the Paleocene epoch of 65 million years ago", as well the "lively prose and sheer imagination".

[3] Norton expanded on this sentiment, writing that Oppel provides "a wonderful imagining of a pivotal moment in evolution".
