Mills & Boon bought foreign rights into Australia for a May, 2011 release and they came up with a new cover. I love it. Rights were also sold into France, the UK and Germany. The German imprint is CORA Verlag, the imprint for France is Darkiss which is targeting a June 2012 release. For the UK, Mira Ink bought rights for a May 2012 release. Below are the covers:
From Mills & Boon - Australia - IN THE ARMS OF STONE ANGELS
The foreign cover for ON A DARK WING from Harlequin Australia didn't change much except for the quote from PC Cast.
And below is IN THE ARMS OF STONE ANGELS translated into German with a cover from Harlequin - Germany.
The French translation & new cover are coming a the editions for the UK may not have a cover change.
