Thomas Olde Heuvelt (1983) is the international bestselling author of HEX. The much-praised novel was published in over twenty-five countries around the world and is currently in development for TV by Gary Dauberman. Olde Heuvelt, whose last name in Dutch dialect means “Old Hill,” was the first ever translated author to win a Hugo Award for his short story "The Day the World Turned Upside Down". His new novel ECHO will be out with Nightfire Books in the US and Hodder & Stoughton on February 8, 2022. International publication of his novel ORACLE, which topped all the bestseller charts in The Netherlands in March '21, will follow soon thereafter. Thomas lives in The Netherlands and the south of France and is an avid mountaineer. Praise for HEX: “This is totally, brilliantly original.” —Stephen King “Creepy and gripping and original.” ―George R.R. Martin “Spielbergian in the way Olde Heuvelt shows supernatural goings-on in the midst of everyday life... It’s a fabulous, unforgettable conceit and Olde Heuvelt makes the most of it.” ―The Guardian
