Do you see an increase in the paper version of the first book in the series? The problem with Sunborn is that it's book 4 of your series and if I was to recommend it to a friend I would start them off with book 1. So if freebie ebooks were to help your paper sales I would probably gauge the sales of the earlier books since that is where new readers will probably be starting from.

If my friends were into ebooks then I would've shown them the first three novels offered as freebies and they probably would've picked up Sunborn as a freebie as well or purchased it as an ebook and not the paper version.

In my opinion, the trend is to move away from paper version of books and to ebooks so for those who are already into ebooks, I don't see a reson for them to pick up a paper version too. For those that are not into ebooks, then I see them picking up the earlier titles in paper form after someone who read your ebook freebies and recommended the series.

Since there was such a large time gap from the publishing of book 3 to book 4, the publishers could've republished the first 3 books as an omnibus edition or rebundled the first three for a cheap price the months prior to the launch of book 4. That would've probably help increase the paper sales of book 4 immediately.

Free ebooks probably will increase the sale of your current and future ebook sales. I don't really see it impacting the paper versions unless you be really mean and gave feebies of books 1-3 and book 4 was to be released in paper form only.

All this is of course just my opinions. =)
