Hey Richard, glad you're enjoying it!
When Mike wrote the In Her Name series, he actually pulled a Star Wars. He wrote the original series, what is known now as the Omnibus, in the early to mid-'90s, and only published it when self-pubbing became possible with the Kindle in 2008. After people started reading it and enjoying it, they started asking for more, more, more on the Kreelans and how the whole thing started, so he went back and started writing the Prequel Trilogy, which consists of First Contact, Legend of the Sword and Dead Soul which will be released in the fall. He also plans on writing a third trilogy which will span from Dead Soul and take us up to where Empire begins, or at least up to the point where we'll meet Reza's parents.
Mike has thought about adding the numbers to the titles, but at this point, he feels the work and time involved in re-doing the covers and re-uploading them is more profitably spent on writing. He's still working his full-time job (though he will be quitting in mid-August to write full-time!), so time is precious of course. But what he does try to do is list in the descriptions for all of the books the reading sequence. He has to get on the ball and make those changes on Smashwords. He is hoping to get to that today. Thank you for the push on that!
HTH! Let me know if you have any other questions. And enjoy the series!
