For anyone that was wanting to get Blood Slave via Amazon, I am sorry to say that it will not be available there.
Evidently, the content violates the TOS Amazon has. Not sure how, since it was just published there when it was out with Phaze, and I have read some stuff published via Amazon that is a whole lot edgier than Blood Slave.
But, ah well ... they get to choose what they want to offer on their site.
So, if you are wanting a mobi format, I guess you will have to check out All Romance eBooks.
