Relentless is about author Cubby Greenwich, who has just published the latest in a string of successful novels. It gets panned by one particularly vicious critic, who turns out to be more than just a critic. Cubby and his family end up on the run, relentlessly pursued by the murderous critic.
I have been a fan of Dean Koontz for more than 20 years and I'm happy to say he just keeps getting better. Relentless is classic Koontz--a genuine thriller with quirky characters you care about (including a great dog), plenty of humor, and just a touch of science fiction. It's very well done.
