Sacrificed to Beasts is the first volume in the Marked by the Beast Erotica Series and is available now on Kindle. Vol.2, Seducing the Beast, will be available in early November 2013.
A word of warning: The men in this series are not called "Beasts" lightly. They have some extremely inhuman qualities which some readers may find disturbing in the context of an erotic story. If you prefer your erotica traditional, this may not be your cup of tea.
