If you've never read a Lee Child novel but have seen the trailers for a film starring Tom Cruise… can I seriously suggest you read at least one of the books before seeing the film. To be fair, I haven't seen the film and Cruise might do a decent job of whatever script they've given him… but Jack Reacher he isn't.
If you enjoyed this, then obviously the rest of the Reacher series is a must… [[Never Go Back by Lee Child|Never Go Back]] for instance, and of course the current master of the genre has to be Harlan Coben [[Tell No One by Harlan Coben|Tell No One]] being as good a place as any to start with him.
