Our view
“Life Expectancy” is an offbeat, twisty Dean Koontz novel that mixes suspense with a strong vein of humour. The story turns on five decisive moments in the life of James “Jimmy” Tock, a self-described lummox. Some readers relish its absurd, unpredictable streak; others single out the surprises and the comic spark of Lorrie, a character they warm to. Nearly five hundred pages long, it is for readers who like their thrillers with a wink.
