The serpentine story — narrated, for once, by Reacher himself — stretches all the way back to Afghanistan in 1983 where the Russians were defeated by the mujahideen. The moral, if that is not too strong a word for such a bloody, brutal tale, is that: "Sometimes our friends become our enemies, and sometimes our enemies become our friends." Reacher does not reveal much about himself, apart from a liking for rats and guns, yet this simply enhances his status as a mythic avenger. Gone Tomorrow will be appreciated by those who consume thrillers for the same reason that our hero drinks coffee: "It's about the caffeine & not the taste." You'll be left with a thumping heart and a racing pulse but, be warned, Chapter 63 will give you nightmares.
