Thomas Olde Heuvelt is an international bestselling author from The Netherlands. His breakthrough novel Hex was published in over twenty-five countries and hailed as 'totally, brilliantly original' by Stephen King and as 'phenomenal, phenomenal' by film director Mike Flanagan. His follow-up novels Echo and Oracle have since seen global publication, the former boasts, according to the Guardian, 'possibly the most frightening prologue ever written', while the latter was judged by The New York Times to be his 'sharpest, most compelling work to date'.

Olde Heuvelt, whose last name in Dutch dialect means 'Old Hill', was the first translated author to win a Hugo Award (for his short fiction, in 2015). He lives in The Netherlands and the south of France with his partner, author and photographer David Samwel. Aside from being a writer, he is an avid guitar player and mountaineer.
