Ng's 2017 debut novel Under the Pendulum Sun (published by Angry Robot)[3] concerns a fantastical journey in gothic mid-19th century England,[7] and was shortlisted for Starburst's 2017 Brave New Words award[8] and the 2018 Robert Holdstock Award for Best Fantasy Novel at the British Fantasy Awards.[9] It was named by Syfy as one of the "10 Best Sci-Fi and Fantasy Books of 2017"[10] and included in Adam Roberts' list of "The best science fiction and fantasy of 2017" in The Guardian[11] and Jeff Somers' list of "50 of the Greatest Science Fiction & Fantasy Debut Novels Ever Written."[12]
Ng won the Sydney J Bounds Award for Best Newcomer at the 2018 British Fantasy Awards for Under the Pendulum Sun,[13] and was a 2018 finalist and 2019 winner of the John W. Campbell Award for Best New Writer, announced as part of the Hugo Awards.[14]
Her story "How the Tree of Wishes Gained its Carapace of Plastic" is included in the anthology Not So Stories, published April 2018 by Abaddon Books,[15] and was described by Starburst as "a tour de force of the author's talents."[16] Other short stories have been published in Mythic Delirium[4] and Shoreline of Infinity[17] magazines.
As part of her acceptance speech, she referred to the award's namesake John W. Campbell as "a fucking fascist", sparking debate in the science fiction and fantasy community.[20][1]
In July 2020, Ng was awarded the Hugo Award for Best Related Work for her 2019 John W. Campbell Award acceptance speech.[22] In her acceptance speech for this award (delivered by video due to the COVID-19 pandemic), she said that "pulling down memorials to dead racists is not the erasing of history, it is how we make history". She also said that "Last time I gave a speech at WorldCon, it was literally hours after a huge march in Hong Kong, my most cyberpunk of cities. Since then, things have gotten worse." "The tactics used to marginalise us, the tear gas used against us, it is the same everywhere. And we defeat it in the same way. And so our coming together is more important than ever before. To write a future of joy and hope and change." "Now is the time. Now is always the time. Free Hong Kong, Revolution of Our Time."[23]
