It’s May the 5th.
May 5th this year is release day (sometimes called ‘book birthday’ on the internet) for Oracle.
I know that a few of you have already found the book in the wild; when I went into the bookstore on Saturday, I found it :D.
This year, for the first time, the ebook for people who are not living in North America is also available. Or will be, within the next few hours (it has gone live on Kobo, which usually takes longer, but not yet live on Amazon or iTunes).
In fact, all of The House War books that currently exist are now available as ebooks for people who live outside of North America. They are not available on Smashwords, because Smashwords requires World Rights for the books uploaded through them, and I don’t have World Rights; I have been very grateful that DAW has published those books in North America.
