For those that enjoyed the Reacher novels (Lee Child) and Harry Bosch series (Michael Connelly), try John Sandford, both the Lucas Davenport series and the Virgil Flowers books. Also liked David Baldacci Camel Club series and King and Maxwell books. Just started in on Harlan Coben. Read the Myron Bolitar books, thought they were OK.
Another light read that's pretty good is Kevin Hearne's Iron Druid Chronicles.
