An award-winning freelance writer based in Toronto, King of Infinite Space is Siobhan Roberts's first book, publishing fall 2006 with House of Anansi in Canada, Walker & Company (Bloomsbury) in the U.S., as well as with publishers in Italy (Rizzoli), Japan (Nikkei), and Korea (Seung San).

Her work focuses on reconciling what the British novelist and scientist C.P. Snow famously referred to as "the two cultures," science and art.

Roberts writes for numerous scientific and general interest publications including SEED, The Walrus, Toronto Life, Saturday Night, Canadian Geographic, and The Mathematical Intelligencer, as well as the Globe and Mail and the National Post (she was employed as a national reporter and feature writer at the Post from 1999-2001).

Her profile of Donald Coxeter, "Figure Head," appeared in Toronto Life and won a National Magazine Award, as did her Saturday Night article "Broken Records" (focusing on Canada's National Archives, it investigated the future of the past and how new technology is endangering rather than enhancing the preservation of archives).
