A late update, I waited until tonight hoping that iTunes/iBooks would get Shattered Ties live sometime today. It looks like that isn't going to happen. The approval queue there generally takes about a week, sometimes a little less, sometimes a little more.
I loaded it up on Thursday or Friday of last week (I'm not positive which day as I'm a little punch drunk tonight). I figured that would give enough time to get it live before the release date as it was a little more than a week.
It turns out that wasn't enough time. There were a few issues on my side that led to this one not being loaded up as soon as it should have been, so I'm re-working the process on my side to make sure that I get subsequent books loaded up at least 2-3 weeks before the release date.
Shattered Ties is up now everywhere else (links below), but I'm very sorry for all of you Apple users who are going to have to wait for an extra few days. I'll do a new post as soon as it goes live as well as a tweet and a e-mail blast as soon as it goes live for you guys.
