A must-read thriller from Dean Koontz - the worldwide bestseller of over 400 million copies.
RELENTLESS is a pulse-pounding, page-turning race to the finish.
It looked like just a bad review. But perhaps it was a death threat... Being a writer is a dangerous business. When Cubby Greenwich receives a scathing review for his latest bestseller by the feared and therefore revered critic Shearman Waxx, he is determined to take no notice of it. But Fate carries him right into Waxx's path.
What began as an innocent and unexpected encounter is about to trigger an inferno of violence.
For Shearman Waxx is not merely a ferocious literary enemy, but a ruthless sociopath, and now he is intent on destroying Cubby and everything he holds dear: his home, his wife, his young son, and every hope he had in the world. The terror has only just begun, and it will be relentless...
