Your typical Dean Koontz story: Ordinary Man finds ordinary life turned upside down out of nowhere by Pure Evil, in an event that is usually inexplicable and/or random. Most of book involves Ordinary Man being chased by Pure Evil. Along the way he finds or confirms his True Love. In the end, Pure Evil is destroyed, Ordinary Man is (re)united with his True Love, and everything ends happily.
In Ticktock, Vietnamese-American Tommy Phan discovers a strange ragdoll on his doorstep which turns into a demon trying to kill him. Most of the book is spent on Tommy and his newfound love Del fleeing from said demon. Del is extremely mysterious in what I suppose was meant to be an amusing way, but I thought she was really obnoxious, and I couldn’t figure out what Tommy saw in her. On the other hand, I loved Tommy’s mother.
Yes, the story is a tad silly (Del’s secrets, when finally revealed, are even sillier), but it’s Koontz. If you like Koontz, you’ll like this one. It’s a fun, light read.
