Both series are narrated by RC Bray. The series each have different authors but I have noticed some similarities between the two A.I. characters. Anyone else notice the similarities between Skippy and Agatha  and Charles and Veronica ? Please discuss.

I've not read the other book but did get through about half of Expeditionary Force  series and it started out painfully amateurish.   I'd suspect within that genre there is a lot of intermingling of ideas. These books will never push a Mark Twain story out of the Top 100 list so as long as they are entertaining a little leeway must be allowed.
