Crucible is now available on Kobo and Apple iBooks!  Barnes & Noble, Sony, and Diesel Ebooks should be ready soon.  If you are looking to get Embrace on Kobo, I am still working an issue there.  The price is wrong and sample version still showed the older version that some changes for formatting and the preface, among other things.  I am working with Smashwords on the issue.  I recommend you get Embrace directly from Smashwords and use the Epub version if you normally use Kobo.
