For Rolling Stone, Colapinto wrote feature stories on a variety of subjects including AIDS, kids and guns, heroin in the music business, and Penthouse magazine creator, Bob Guccione.
The story, which detailed not only Reimer's tortured life, but the medical scandal surrounding its cover-up, won the ASME Award for reporting.
A newspaper feature story in The Globe and Mail gave an account of the novel's universal rejection in Colapinto's adopted country.
[3] A highly positive review in the Toronto Star called Undone "an equally inventive but bolder novel" than Colapinto's debut; a review in the Globe and Mail called the novel "a noir that, like Francine Prose's Blue Angel and Philip Roth's American Pastoral, details the unravelling of the moral American man and his world."
Trade magazine Booklist gave the novel a starred review that said: "Cannily over the top in its comic depravity and magnetizing in its sympathy, Colapinto's battle royal of innocence and evil, blindness and illumination, betrayal and love will thrill those who enjoy subversively erotic and suspenseful fiction of the finest execution and most cutting implications."
As a staff writer for The New Yorker, Colapinto has written about subjects as diverse as medicinal leeches; Sotheby's auctioneer Tobias Meyer; fashion designers Karl Lagerfeld and Rick Owens; the linguistic oddities of the Pirahã people (an Amazonian tribe); and Paul McCartney.
