I'm a big fan of Tom Clancy's [earlier] works, have read most of Vince Flynn's series, loved Robert Ludlum's work before he passed, and have started Brad Thor's first novel, The Lions of Lucerne. I love the Thriller genre. I'd like to know if there are any really good works that any of you can recommend. I know there are authors in this genre that I've never heard of, and I'm interested in expanding my reading beyond the big five or ten Thriller writers out there. Any recommendations? Thank you.
