Just got this email from ACX (Audiobook Creation Exchange):

You have approved the audiobook production of “House of Cuts (Hillary Broome Novels)”. Thanks! ACX will put the audiobook through a final quick quality control process, and then begin distributing it to Audible.com, Amazon.com, and iTunes. Barring any issues in the quality check, that process should take around 2-3 weeks. In the meantime, check out the Promote Yourself section of ACX.com to learn about simple ways to promote your audiobook and increase your sales!
Sincerely,

The Audiobook Creation Exchange Team
