Another Koontz book read, and this was the longest by a good way.
If you want a holiday read this is not it, but at 800 pages, this sure is value!

False memory starts with 4-5 page long chapters. This is not that conducive to getting stuck into the book.
I know a few others who have started this one, and stalled.
However, take my word, False Memory is more than worth persevering.

The idea is that at the start, you are introduced to the characters of the book a little at a time. Each chapter is devoted to first a couple, Dusty and Martie, then Dusty's brother Skeet, then a loony Doctor of psychology with a nasty style of patient care!
Guess who the baddie of the book is?

We soon learn that Dusty and his close ones share a linked loss of minutes of each of their days. Skeet has a nasty fall off a roof, after which he knows little.
Then on the same day, Martie starts acting paranoid about being dangerous with anything sharp, which comes to hand.
Meanwhile the Doctor, Ahriman, using Haiku (a form of Japanese poetry), is gaining control of Martie's best friend Susan’s mind. We soon learn just how much power he can exert, and then join Dusty and Martie on a journey to discover exactly by whom, how and why they are being used like this.

Fans of Koontz will perhaps find the ending lacking in any hugely shocking supernatural or bizarre twist. However, it does have a series of huge twists for our friends, all of which completely change the previous perception o False Memory.
I have to say that I could not work out how this was going to end at all, and was gripped finding out.

Quite a hard read maybe, but worth the effort.
