I love all of Dan Brown's books, and I'm getting into David Balacci, does anyone know any other writers with a similar style to them? (and anyone who doesn't include a lot of romance in thier books? I'm not big on that)

Thanks!

Greg Iles is a good one. If you like CSI like books, Tim Brown's Bugman series is awesome. Also Jeff Deaver. Legal mysteries, John Lescroart or James Grippando, although I don't have much input from him yet, as I have only read one book.) James Swain w/Midnight Rambler was very good. You might like even better Steve Berry and his Cotton Malone mysteries.  My husband loves his books, I liked The Templar Legacy and The Third Secret and then he loses me after that. He does alot of historical background in his book, so if you like that you might like them all.

Michael Connelly's Harry Bosch series or David Morrell's books may interest you. I haven't read Dan Brown, but I have read David Baldacci and enjoyed his Camel Club books.

Thank you guys, I will definintely be cheacking them out! I'm glad I have so much free time this summer to read!

Everyone here is giving you great suggestions!  Just for fun, try literature-map.com some time.  I don't always agree with their comparisons but it is kind of fun to watch the screen.

Another vote for Michael Connelly.  Also, John Sandford, Robert B Parker and Stuart Woods early books.

Awesome, thank you!!

I like Harlan Coben and Mark Gimenez as well.

And Philip margolin.
