I am a rabid reader of detective/spy/action thrillers and am looking for new books to read. Tom Clancy and Robert B. Parker were my favorites and I have read all of Grisham, Baldacci, Le Carré, Forsythe, Higgins, Ludlum, et. al. Do you folks have any recommendations for a desperate fellow looking for authors I haven't tried. What can y'all tell me about Mark Greaney's and Brad Parks' books?
