This is a slightly complicated answer. Ready?
For Samhain, any book over 50K (which is all my Men of Honor and Phoenix, Inc, books except for Ties That Bind) go to print approximately 10 months after the publication of the eBook.
For Riptide, any book that qualifies, length-wise, for print will come out in print and eBook at the same time. For right now, this list includes:
the 3rd and 4th Hell or High Water Books, Dirty Deeds 2 & 3 and the Havoc Series, along with the full length.
For the Stolen series, since I self-publish them, these books are available through Createspace (Amazon) in print and everywhere else in eBook.
