Hellbound

Tricked by Peklenc, the demon of judgment, Marowit must spend eternity
judging the souls of the damned and meting out punishments. That is,
until he is summoned by a drugged out mortal for sacrificial reasons and
the mortal's daughter catches his eye. Striking a deal with the mortal,
Marowit returns to Hell with Isabella, a pure virgin soul.

In an attempt to save her sister's life, Isabella Michaelis makes a deal
with a demon to serve him for all eternity if he'll just spare her
sister's life. Part of her finds the demon Marowit oddly charming and
quite frankly, downright sexy enough to make her wonder about her own
sanity, especially once she's in Hell.

Knowing he broke the rules, Marowit's hand is forced to make the woman
he brought down to hell fall in love with him, or forever lose her back
to normality. Yet truly wicked forces are at play behind the scenes.
Can Marowit convince the pure soul to remain in Hell with him or will
they find and lose love?
