From Goodreads "Fans of Nathan Lowell," a post for Captain's Share, by a member named Betsy posted this on Aug 31st, 2010, to clarify an Amazon notice...
"PLEASE NOTE: This book is being added for pre-order purposes and the actual date has yet to be determined. We (the publisher) are still waiting on a final manuscript from the author, and will update the release date as we know more. Please keep in mind that this is an arbitrary date at this point."
But, from Nathan's own blog, dated Aug 29th, 2012, he states...
I sent the draft to Ridan in June. They haven’t gotten it back to me yet. There’s a stub in Amazon for pre-orders, but that’s only for paper. So far we still cannot set up a preorder for ebooks. I’m guessing that —unless they accept the manuscript I sent without any edits — we’re not going to make the Sept 1 date.
There seems to be a discrepancy between Ridan and Nathan about getting the manuscript. Ridan says they are waiting for the manuscript and Nathan says he sent it in June and has not heard back from them. So, from Nathan's comments, he has not even gotten the edits back yet, unless, as he noted, they are going to release it as is...
You got to admire Nathan's fans, they are a patient bunch.
