I didn't see "Meteor" mentioned with all the Dan Brown books. That was not bad - but out of content to DaVinci Code.
If you like historic books, try Mika Waltari and Peter Berling. Their books are great, read them in german and some in english too.
I have read all their books and i loved them all.
If you start Peter Berling, see that you get them straight in a row.
