Again the only information I have to offer on the author is her real name and the fact she penned a number of similarly minded novels. Which, again, is more than I know about the cover artist, despite the fact there's a blurry signature on the front.
(My best guess is Santopadre; possibly Santapadre or Santepadre. Unfortunately, as of this writing, I had no luck finding info. on any of the three but I'll let you know if that changes.)
