They're decent, but it's basically the same story over and over. There's something to be found (in most cases archeological or technical). The Rosslers are always involved in some way in the finding. There's a group that opposes them (either in trying to block them from finding information or in trying to ferret out information that they can use for nefarious purposes). By book 4, I was ready to be done.

I wish there had been more puzzles that the reader could help solve (more on the lines of "The DaVinci Code") rather than just reading along. The author took a while to develop the characters into people I cared about. I didn't like that Daniel and Sarah slept together before being married. ( )
