I see that the band Her Whisper changed their name to Disconnected, then to Sinners Paradise.

Did Sinners Paradise ever release an album under their new name?

There is no entry for Sinners Paradise in Metal Archives, and I haven't been able to find any albums from them. (I already know of the two albums released under the name Her Whisper, with "The Grand Unifier" being the last one released under that name.)

The only thing I found was a news story mentioning that Sinners Paradise was expecting to release their debut album, called "The Awakening", in 2009. However, I haven't been able to find a copy of the album and I can't tell if it was ever released. Did this ever get released? Does it actually exist? Is it available anywhere?

Not to my knowledge. They did change their name to Dark Design and released "Time Is an Illusion" (which might have been the material they recorded under the Sinners Paradise moniker). They don't seem to exist anymore.
