Blue Moon by Lee Child. Jack Reacher is at his monosyllabic best taking on warring Albanian and Ukranian mobs in an unnamed city. He initially gets into trouble doing a good deed for an elderly couple that becomes the first step in a trip down the rabbit hole of vicious loan sharking. Naturally, there is a sexy waitress, multiple gun battles and lots of driving around. Even though this all sounds hopelessly trite, Child is a master at writing page-turners and developing enough new twists that you can’t put it down.
