Boy Swallows Universe is the debut novel by Australian writer Trent Dalton. It was originally published by Fourth Estate in Australia in 2018.^[1]

This semi-biographical^[2] coming-of-age novel is set in Brisbane, Queensland, in 1983. Eli Bell is a traumatised teenager with an absent father, a mute brother, an imprisoned mother, and a heroin dealer for a stepfather.

After its original publication in 2018 in Australia by publisher Fourth Estate^[3] the novel was later republished as follows:

• HarperCollins, US, 2019^[1]
• Fourth Estate, Australia, 2019, 2023^[1]
• The Borough Press, UK, 2019, 2020^[1]

The novel was also translated into Spanish, Swedish, French, Dutch, Finnish, Turkish, Portuguese, Chinese, Czech, and Lithuanian in 2019; Italian, Polish, and Russian in 2020; and German, Korean, Japanese and Hebrew in 2021.^[1] It became the fastest-selling debut novel in Australian history, selling more than a million copies worldwide.^[2]

John Collee in The Age compared the writer to Tim Winton and Robert Drewe, stating: "Dalton is a writer in the same league. His dialogue is every bit as funny and accurate as Winton's, his prose just as evocative, and he's better at wrapping up the ending. The last 100 pages of Boy Swallows Universe propel you like an express train to a conclusion that is profound and complex and unashamedly commercial. There are shades of Raymond Chandler in the final confrontation with the town's bleached and wealthy benefactor whose cement bunker conceals a chilling secret. And even a nod to John Buchan."^[4]

Sunil Dasgupta writing in the Washington Independent Review of Books noted: "This is Dalton’s debut novel, and he is a compelling storyteller with an exceptional voice. He depicts a heroin-addled Australia that we are not familiar with in the United States, a perch from where Australia looks like all gorgeous beaches and even more gorgeous beach bums."^[5]
