'[A] touch of strangeness, of alienness, avoiding sub-Stephen King clichés. [Olde Heuvelt] has written five novels already, and publishers should be lining up to translate them.'

- John Connolly

- Jeffrey Ford
'HEX is a thoughtful horror story, and one that is all the more chilling for its uncompromising view of humanity. . . . I found the story and its ending uncompromising and inevitable.'
- Robin Hobb

- Sarah Lotz
'Thomas Olde Heuvelt’s HEX is a treat for all fans of dark fiction . . . a modern spin on the witch’s curse story that forces us to take a closer look at ourselves. Who is really evil after all? It’s may not be who you think. This is just the beginning and I can’t wait to read his next one.'
- Ann VanderMeer
'Hidden tensions and human weakness trigger a witch-hunt that boils over into persecution, scapegoating and a shocking denouement. A powerfully spooky piece of writing.'
- Financial Times
'The best horror debut since John Ajvide Lindqvist’s Let the Right One In.'
- Alan Kelly, Rue Morgue
