I read The Darkest Evening of the Year and finished it on Saturday. It's pretty good; one of Koontz' spiritual horror novels, and a love story to golden retrievers.
Amy runs a golden retriever rescue and her partner, Brian is an accountant.
A seemingly ordinarly couple but they both have very deep, dark secrets.
And when Brian's unstable ex-girlfriend Vanessa gets in touch, things are about to get very dark indeed.
Readable, suspenseful and somewhat sad. :)
