Life Expectancy by Dean Koontz

With a so-simple-it's-brilliant plot, snappy dialogue that would easily transfer well to the big screen, and characters who are as believable as they are likable, Life Expectancy is a literary dramedy with equal parts tension and humor that make for a frantic and fun ride through the blessed/cursed life of Jimmy Tock, pastry chef.
Born at the exact same time as his grandfather's passing (and just after the old man's prediction of five specific future dates that would be "terrible days" for Jimmy), Tock tells the story from the first person perspective (a vantage point I usually don't like in fiction, but Koontz pulls it off well), recounting in detail the aspects leading up to and surrounding each of his particular bad days. The story's peaks and valleys rise and fall with the proximity of the past or next approaching date, and you can almost feel yourself gearing up along with Jimmy and his family in preparation for what might come.
Along the way, Koontz introduces us to a colorful cast of characters - Jimmy's parents, lovable and actually functional, despite their keeping baker's hours and caring for their ultra-opinionated Grandmother Rowena; Konrad Beezo, the killer clown with revenge on the brain, who has much to do with Jimmy's five terrible days; and Lorrie, Jimmy's eventual wife and mother of his children, who comes off as witty, beautiful, and smart as Jimmy repeatedly says she is. (Note: Others are involved, but mentioning them would spoil the plot; rest assured, more personalities means more fun in Koontz's world.)
The story ebbs and flows in all the right places, the surprises (and there are several) are genuine, and the ending is both satisfying and sweet, wrapping up a strange, silly story you'd never believe, except for the fact that Koontz makes you believe it through his storytelling. This is what page-turning bedtime fiction is and should be.
